Preheat your oven to 375 degrees F.
Prepare an assembly station with two casserole dishes, the cooked seasoned meat, bowl of shredded cheese, pot of homemade enchilada sauce, and any other optional fillings or toppings.
Add about 2-4 tablespoons of the enchilada sauce to each baking dish.
Take half of the tortillas and dip one side in the sauce and place at the end of the first pan. Continue to dip each tortilla in the sauce on one side then stack them on top of each other. Repeat with the rest of the tortillas in the other casserole dish.
Take the first tortilla and fill it with 1 1/2 to 2 tablespoons of the cooked meat spread down the center of the tortilla. Sprinkle one or two pinches of grated cheese over the meat. Roll the tortilla over the meat and place seam side down in the pan. Hold the first tortilla in place so it doesn't unroll while you begin rolling the next enchiladas. Once you finish filling and rolling the enchiladas, adjust the arrangement of the rolled tortillas so they are spaced equally.
Repeat with the second casserole dish.
Pour the remaining enchilada sauce over the rolled enchiladas and spread with a spatula so all the tortillas are covered completely with sauce. Top with the rest of the shredded cheese and optional sliced olives.
Bake 20 minutes then rotate pans and bake for an additional 10-15 minutes.
Cool for 5 to 10 minutes then serve with sour cream, fresh cilantro, sliced green onion, beans (black beans or refried beans), and/or Mexican rice.
