Slice the cauliflower head in half, then quarters. Cut the stem at a 45° angle and separate the florets.
Grate the cauliflower using a box grater or use a food processor (my preference). To do so, add the florets to the food processor jar in two batches. Pulse till the cauliflower breaks down into rice like crumbles. Alternatively, attach the grating blade. Turn on the processor and start adding the florets through the feeder tube. You may have to cut the larger florets so they fit in the tube
Heat olive oil in a large skillet on medium-high heat. Add finely chopped onion, minced garlic and sauté for 1 minute.
Add the cauliflower rice, salt and pepper to the pan and sauté for another 4-5 minutes or until it cooks to your desired texture. Turn off the heat.
Stir in lime zest, lime juice and chopped cilantro. Toss everything till it combines well. Enjoy with your favorite Mexican entree!
Cauliflower: Use a whole head of fresh cauliflower. To replace a medium size cauliflower, use 1 ½ bags (16 oz each) fresh or 2 bags (12 oz each) frozen cauliflower rice. No need to thaw if using from frozen.
Limes: Look for limes that are plump and heavy for their size. If they don't seem juicy enough, pop them in the microwave for 20-30 seconds to allow the juices to flow.
Cilantro: Use as much or as little as you like. Just make sure to trim the bottom 2 inches of the stems before using.
Use a Box Grater: Grate the cauliflower on the medium holes of a box grater. This is a good alternative if you do not own a food processor. It will take more time, but it gets the job done.
Squeeze out the Excess Moisture: Although not necessary, if it appears to be more moist, feel free to squeeze out excess moisture from the riced cauliflower (either homemade, fresh or frozen) with a clean kitchen towel. This helps prevent it from becoming soggy.
Make Ahead: The rice will keep in an airtight container in the fridge for up to 4 days or in the freezer for up to 1 month. Reheat in the microwave or over medium heat on the stove until warmed through.
