Step 1: Prepare the Cauliflower Rice: If using a whole head of cauliflower, remove the leaves and stem, then cut it into florets. Using a food processor, pulse the florets until they resemble rice grains. Alternatively, you can use pre-riced cauliflower for convenience.
Step 2: Cook the Cauliflower Rice: In a large skillet, heat the olive oil over medium heat. Add the riced cauliflower and sauté for about 5-7 minutes, stirring occasionally, until tender and slightly golden.
Step 3: Season the Rice: Stir in the garlic powder, onion powder, cumin, paprika, salt, and pepper. Cook for another 2 minutes to allow the flavors to meld.
Step 4: Add the Toppings: Once the cauliflower rice is cooked, add the black beans, corn, and diced bell pepper to the skillet. Stir to combine and heat through for another 3-4 minutes.
Step 5: Assemble the Bowl: Divide the cauliflower rice mixture into bowls. Top with sliced avocado, fresh cilantro, and a squeeze of lime juice for added flavor.
