01 - In a large oven-proof skillet over medium-high heat, cook the ground beef, breaking it apart, until well browned. Drain off excess fat if needed.
02 - Add diced onion, minced garlic, and red bell pepper to the skillet. Sauté until vegetables are softened, about 3 to 4 minutes.
03 - Stir in drained black beans, ground cumin, chili powder, smoked paprika, salt, and black pepper, mixing thoroughly.
04 - Pour in enchilada sauce and tomato sauce. Stir to combine all ingredients evenly.
05 - Layer half of the cut corn tortillas over the beef mixture. Sprinkle with half of the shredded cheddar and Monterey Jack cheese.
06 - Top with the remaining corn tortillas and the rest of the shredded cheese.
07 - Reduce heat to low, cover the skillet, and simmer for 5 to 7 minutes until cheese is melted and mixture is heated through.
08 - If desired, place the skillet under the broiler for 2 to 3 minutes until the cheese turns golden and bubbly.
09 - Garnish with green onions, cilantro, sour cream, or diced avocado as preferred. Serve hot.
