In a small mixing bowl, add chopped onion, tomato, green chili, cilantro and toss it with chaat masala. Keep aside.
Adjust the idli-dosa batter consistency to match a pourable waffle batter consistency (not too thick or thin)
Preheat your waffle maker as per your brand's instructions. Lightly grease the waffle plates using olive oil or avocado oil.
Pour about ¼ cup batter in each cavity. Adjust according to your waffle maker.
Top with 2 tablespoons of the veggie mix. Adjust this quantity to your taste.
Cook the waffles as per waffle maker's instructions. For my model, it takes 4 minutes 30 seconds for the waffles to be done. Once done, use a wooden spatula and carefully remove the waffles.
Allow them to cool for 2 minutes before serving. In the meantime, repeat the process and make more waffles. When cooled, cut the waffles and serve with the chutney of your choice - coconut, cilantro, tamarind or good ol' ketchup.
Notes
Add a few tablespoons of water to reach the right batter consistency. You're looking for the consistency of a traditional waffle batter (not too thin, not too thick). I use about 1-2 tablespoons of water.
Each square waffle needs ¼ cup batter or ½ cup total at one time. My waffle iron has two square waffle cavities, so I place ¼ cup batter into each. This comes out to ½ cup batter total. However, since some waffle makers come with two or four cavities, and square or round shapes, adjust the quantity accordingly.
Cook time will depend on your waffle maker. It takes 4 minutes, 30 seconds for my waffles to fully cook. Adjust the time based on your waffle maker. If the waffles are golden-brown and spring back to the touch, they're ready!
Keep the waffles hot in a warm oven. Place the cooked waffles on a wire rack on top of a baking sheet and keep in a 200 degree F oven while you prepare the remaining batter.
Meal prep for a quick lunch or snack throughout the week. The waffles will keep for up to 4 days in an airtight container in the fridge. Enjoy cold, room temperature or re-warmed for 3-4 minutes in the oven.
