When it comes to an easy low-carb side dish, it doesn't get much better than this authentic Mexican cauliflower rice. Who knew that a rice substitute would taste this amazing?

Ingredients
You can use homemade cauliflower rice, or bag riced cauliflower. The other fresh items that infuse this dish with flavor are onions, jalapeño (optional to add some spiciness), bell pepper, garlic cloves, tomatoes, lime (the juice adds incredible flavor), fresh cilantro, and avocado for topping. You’ll also need some olive oil to cook up the veggies, and cumin, paprika, and salt for seasoning.

Fresh or Frozen Cauli Rice
You can use fresh or frozen cauliflower rice; both perform great. If you're short on time, using frozen cauliflower rice is a great option; just make sure to thaw it first and ring out any excess water before cooking it.
How to Make Mexican Cauliflower Rice
- Rice the cauliflower.
If using a head of cauliflower, make cauliflower rice in a blender or use this method to make cauliflower rice with a cheese grater. - Cook the vegetables.
In a large skillet, sauté chopped onion, jalapeño, and bell peppers for 3 minutes, until softened, then add garlic and chopped tomatoes and cook for 2 minutes. - Cook the cauliflower rice.
To the skillet, add the cauliflower rice and stir to combine with the veggies. Add the seasonings and continue stirring while the cauliflower rice cooks down for an additional 4 to 5 minutes. - Add lime juice and serve.
Turn off the heat and squeeze half a lime and mix to incorporate it into the cauliflower rice. Garnish with cilantro, avocado, and a slice of lime.

How Spicy is Mexican Cauli Rice?
Just like the traditional Mexican rice, this Mexican cauli rice is mild in flavor. That said, you can spice it up by adding extra jalapeños or swapping the smoked paprika for spicy paprika.
What to Serve with Mexican Cauliflower Rice
Some of my favorite pairings with this rice substitute are Auntie's Mexican chicken tacos, rotisserie chicken enchiladas, Mexican vegetable bean soup, and the juiciest baked boneless skinless chicken breasts.
