Preheat oven to 350 degrees Fahrenheit.
Coat a 9x13 Pyrex baking dish with Pam cooking spray. Then coat bottom of pan with 1-2 tbsp. of the salsa. Using a clean dish towel, wrap corn tortillas and cook in the microwave for 1 minute until tortillas are soft and will bend without breaking. Fill each tortilla with ¼ to ½ of a cup of the shredded meat (can be still cold from the fridge) and a sprinkle of the cheese. Wrap up and place in the baking dish. Once all meat has been used (or the dish is full), pour the remaining salsa over the top and sprinkle on the remaining cheese.
Bake for 25-30 minutes until cheese is melted and the meat is fully reheated. Serve with diced tomatoes, diced avocado, sliced olives, and plain greek yogurt.
