Preheat oven to 350 degrees. Lightly spray a 9 x 13" baking dish or pan with non-stick cooking spray.

Prepare the seasoned ground beef; in a large skillet, brown the ground beef over medium-high heat and drain off any excess fat that is rendered. To the drained ground beef, add the taco seasoning, tomato paste and water. Heat over medium-high heat and simmer for 3-5 minutes or until most of the water has evaporated. Remove from heat and set seasoned meat aside.

To the bottom of the pan, place a single layer of 3-4 tortillas. Cut a couple of the tortillas in half, if needed to prevent any overlap. On top of the tortillas, add about 1/2 cup of the seasoned ground beef, 2-3 tablespoons of the black beans, 1 tablespoon of the chilies, and about 1/2 cup of the enchilada sauce. Sprinkle this layer with about 1/2 cup of the shredded cheese.

Start another layer by placing another single layer of tortillas on top of the fillings, and repeat the process.

Finish the casserole by adding a final layer of tortillas, sauce and shredded cheese.

Bake the casserole at 350 degrees for 25-30 minutes uncovered, or until the cheese has completely melted.

Remove from oven. Let set for 5 minutes before slicing. Serve with your favorite Tex-Mex toppings.
