Preheat oven to 350°F and spray a large 9x13 inch casserole dish with cooking spray. Set aside.
Heat olive oil in a deep saute pan over medium heat. Sprinkle both sides of chicken breast with cumin, garlic powder, salt and pepper. Add to the pan with olive oil and cook chicken over medium heat for 6-7 minutes on each side, or until it reaches an internal temperature of 165°F. Remove chicken to a cutting board to cool. Note 1 for other cooking methods.
2-3 tablespoons olive oil, 1 lb boneless skinless chicken breast, 1 1/2 teaspoons cumin, 1 teaspoon garlic powder, 1 teaspoon salt, 1/2 teaspoon black pepper
To the pan, add the diced onion and garlic and cook, stirring frequently, until onions are translucent and garlic is fragrant. Add the black beans and diced green chiles to the onion and garlic and stir until combined. Reduce heat to low and allow to cook slightly while shredding the chicken.
1 yellow onion, 3 cloves garlic, 1 (15 ounce) can black beans, 1 (4.5 ounce) can diced green chilis
Use two forks to shred each chicken breast then place in the pan with the black beans mixture. Stir to combine. Remove from heat.
Prepare the tortillas by heating them in the microwave for 30 seconds. This softens them and makes them more pliable to work with and roll. Dip each tortilla in a shallow bowl with 1/2 cup enchilada sauce then spoon 1/4 cup chicken and black bean mixture into the tortilla. Fold tortilla over filling and roll up. Place seam down at the end of the prepared baking dish. Repeat the process until all tortillas and filling are used and pan is full of enchiladas.
3 cups red enchilada sauce, 12 whole wheat, grain-free, gluten-free, or corn tortillas
Top prepared enchiladas with the rest of the sauce and top with shredded cheese if using. Bake in preheated oven for 15 minutes or until sauce is bubbling and cheese is melted. Top with garnishes before serving.
1 cup shredded cheddar cheese, Toppings: cilantro, sour cream, diced jalapenos, diced avocado, chopped tomatoes
