Toasted Bombay Masala Sandwich is a pressed-sandwich layered with chutney, aloo masala (spiced mashed potatoes), fresh vegetables, then grilled in a sandwich toaster.

It is essentially a vegetable panini that reigns supreme along the streets of Mumbai, and also referred to as Bombay Toastie and Mumbai Masala Toast!

Fun Fact: Mumbai and Bombay are actually the names of the same city. The original name Mumbai is a tribute to the Koli goddess, Mumbadevi (the city's patron deity). It was first changed to Bombaim, meaning 'good bay' by the Portuguese, then changed to Bombay when the British took over in the 17th century. In 1995, the local political party, Shiv Sena, changed the name back to Mumbai.

The Best Grilled Vegetable Sandwich with Crunch

I love to make these Masala Mumbai Toasts whenever I have leftover boiled potatoes in the fridge or on those lazy Sunday mornings when I have some extra time in the kitchen. They are a delicious savory breakfast, lunch or snack because:

• Potatoes, bread, cheese and vegetables are staples in my kitchen, no grocery run needed.
• The mashed potato filling is a wonderful make-ahead recipe!
• The finishing touch of namkeen provides crunch, texture and fun!
• It's packed with vegetables, cheese and spices for a recipe that is completely Vegetarian (with the option to make it Vegan and Low-Carb, too)!
• It is kids and working-mom approved!

Ingredients - Notes & Substitutions

Today's Bombay Sandwich Toast is the savory version - not to be confused with the popular sweet Bombay French Toast enjoyed throughout India for Sunday morning breakfast. Here's what you need to make these:

For Potato Filling

For the potato filling, simply gather together a few staple Indian spices, potatoes, peas and cilantro.

• Potatoes: Yukon gold potatoes are the best for flavor and texture. I boil them using this easy Instant Pot recipe, but you can use your preferred method too. Some street variations use simple slices of boiled potatoes, but I prefer the extra layer of flavor that this quick 5-minute saute adds to the potatoes.
• Masala Spices:
  • Ginger, black mustard seeds and curry leaves: I add these for their earthy and zesty flavors. If using light mustard seeds, I would recommend using 1.5 times the mentioned quantity. If curry leaves are not easily available, add 1 teaspoon lime juice towards the end instead.
  • The blend of Indian spices like, coriander, cumin and turmeric is based on my family's personal tastes. Chaat Masala is a spice blend I have always have on hand. It adds a zing to the potato filling. If you can't find it, add 1 teaspoon lime zest + 1 teaspoon juice instead.
  • The serrano chili and cayenne flavor the filling to a medium spice level. The spices are then tamed when layered with the bread and cheese. As always, skip the green chili and cayenne for mild.
• Peas: Peas are a traditional ingredient and add a natural sweetness to balance the tangy and savory flavors. I thaw frozen peas, then microwave them for 2 minutes before adding them to the filling.

Once you have the mashed potato filling ready, all you need is butter, bread, crisp, crunchy vegetables, cheese and condiments to spread and serve.

For Masala Toast

• Bread: My family prefers whole grain bread, but use your favorite sliced sandwich bread or whatever you have on hand.
• Condiments: Homemade mint or cilantro chutney is traditional. The ketchup just makes it that much more appealing! Just remember to have extra green chutney, tamarind chutney and ketchup for serving.
• Cheese: Sliced Pepper Jack cheese really makes the chile flavor shine, but a mild or sharp cheddar would be great, too.
• Indian Snacks: This is the fun part! Bhujiya is a crispy Indian dry snack made with chickpea flour and potatoes. Namkeen is the generic term used to describe these savory snack foods. Look for them in specialty Indian grocery markets, the global section of supermarkets or online.

How to Make Bombay Grilled Sandwich

This wonderfully easy and simple Masala toast recipe is ready in under 30 minutes with the help of a panini press and mashed potatoes! If you're short on time, feel free to make the potato filling up to 4 days ahead of time to really get ahead.

1. Make Potato Filling

1. Heat a skillet on medium-high heat. Add oil, mustard seeds and curry leaves. When the mustard seeds begin to splutter, stir in chopped serrano chilies and minced ginger. Saute for a minute (Pic 1).
2. Add salt, turmeric, cayenne, coriander, cumin and chaat masala and saute for 30 seconds (Pic 2).
3. Add mashed potatoes and stir to mix well with the spices (Pic 3).
4. Stir in cooked peas, cilantro and mix to combine. Check for seasoning and turn off the heat (Pic 4).

2. Assemble Bombay Toastie

1. Spread butter on bread slice and invert it on the cutting board so that the buttered side is down. Repeat with all slices (Pic 1).
2. Spread ketchup and green chutney on the other sides. Repeat for all bread slices (Pic 2).
3. Add 2 to 3 tablespoons of the potato filling and spread it evenly on the slice (Pic 3).
4. Layer with a few slices of green pepper and onion, followed by tomato. Sprinkle some chaat masala on top (Pic 4).
5. Layer a slice of cheese. Place the second slice of bread on top, butter side facing up. Assemble the remaining sandwiches (Pic 5).
6. Grill the sandwich in a panini press or a non-stick skillet for around 4 minutes on each side, or until golden brown on both sides. Cool it for 2 minutes, then slice it in half (Pic 6). Serve it as-is or take it to another level by following the next step.

Optional Step: Dress Up the Sandwiches

1. Slice the sandwich in half, lengthwise or diagonally (Pics 1 & 2).
2. Spread a little chutney or ketchup on the cut side of the sandwich (Pic 3).
3. Dip it in a bhujiya or your favorite Indian namkeen mixture (Pic 4).

Serving Suggestions

I love a simple, quick and easy grilled vegetable sandwich for those busy mornings. But on the weekends, I go all out with the 'dressed-up' version.

Once the paninis have cooled for two minutes, I slice, spread and dip in our favorite Indian savory snacks. We like to refer to this as 'Crunchified!' Serve with a side of any of these chutneys: Mint chutney, cilantro chutney or tamarind chutney.

Make-Ahead & Meal Prep

The greatest benefit of this Indian grilled vegetable sandwich is the make-ahead aspect of the filling.

To prepare for the week ahead, I boil the potatoes in my Instant Pot over the weekend, and make the potato filling after that. Then, grill the sandwiches the day I am going to serve. The potatoes and filling mix will keep in an airtight container in the fridge for up to 4 days.

Variations to Try - Vegan & Low-Carb

For a completely vegan Bombay Toast, replace the butter with vegan butter or spread and use Vegan cheese. Alternatively, omit the cheese altogether. The panini press should do a well enough job to stick the sandwich together without the cheese.

For a low-carb version, try mashed cauliflower instead of potatoes and switch to a low-carb or Keto bread instead!

Recipe Tips & Notes

• Serrano chile and cayenne are optional. This will create a potato filling around medium spice level. Keep in mind the bread and cheese will level out the spices. That being said, you can always skip the spicy chilies for mild.
• Mash and prep the potato filling ahead. Store boiled potatoes, plain mashed potatoes or the complete potato filling in an airtight container in the fridge for up to 4 days.
• Make it Vegan. Replace the butter with Vegan butter or spread and use Vegan cheese. Alternatively, omit the cheese completely.
• Go for low carb. Wash, trim and boil one head of cauliflower florets until tender, then mash as you would potatoes. Use this in replace of the potatoes for the filling. Replace the bread with any low-carb/Keto bread of choice.
