Spray a large skillet with non-stick cooking spray and place on stove over medium high heat.
Add tortillas, chicken, onion, and garlic to skillet and cook for about 5 minutes (or until onion is tender and translucent), stirring frequently.
In a medium bowl, mix Rotel, enchilada sauce, black beans, cumin, and garlic powder. Pour mixture over chicken in skillet and mix well.
Sprinkle half of the cheese on top, cover with lid, and let cook for 5 minutes- stirring occasionally. Top with remaining cheese and serve, topped with your favorite enchilada toppings (cilantro, sour cream, salsa, guacamole, etc).
Notes
You could sub out the black beans for pinto beans.If you can't find Rotel tomatoes, a can of diced tomatoes would work great as well. I would recommend adding a small can (4 ounces) of diced green chilies, but it's completely up to you.
