In a large skillet, brown the ground beef or turkey over medium high heat. Drain off any excess grease. To the browned meat, add the Rotel (with the liquid) and the taco seasoning. Check out my recipe for homemade taco seasoning.

Heat meat, seasoning and tomatoes over medium heat until it comes to a simmer, approximately 2-3 minutes. While meat is heating, defrost the cauliflower rice in the microwave for 2-3 minutes, or according to package directions.

To the meat mixture in skillet, add the defrosted cauliflower rice, rinsed black beans and optional hot sauce. Stir together and continue to heat over medium heat for 2-3 more minutes.

To the top of the casserole, sprinkle on the shredded cheese. Turn off the heat and add a lid to the casserole. The cheese will melt within a couple minutes.

Serve with your favorite taco toppings.
