Begin by heating a large skillet over medium-high heat. Once hot, add the ground beef, diced onions, and chopped red and green bell peppers. Cook while stirring frequently for about 6-8 minutes, or until the beef is browned and the vegetables are soft. Drain any excess fat from the skillet to keep the dish light and delicious.

Reduce the heat to medium, and add minced garlic, chili powder, cumin, paprika, cayenne, salt, and pepper to the skillet. Sauté the mixture for about 1 minute until the spices become fragrant and flavorful, making sure to stir well.

Stir in the cauliflower rice and the can of Rotel tomatoes, mixing everything thoroughly. Cook for an additional 2 minutes, allowing the ingredients to blend and heat through.

Add the zero-carb street taco tortillas, folding them gently into the skillet mixture. Sprinkle a generous amount of fiesta blend shredded cheese on top, then turn off the heat and cover the skillet. Allow it to rest for a minute, letting the cheese melt beautifully over the flavorful beef and vegetable blend before serving.
