01 - In a large oven-proof skillet over medium-high heat, cook the ground beef, breaking it up with a spatula until browned throughout. Drain excess fat if necessary.
02 - Add the diced onion, minced garlic, and red bell pepper to the skillet. Sauté until the vegetables are softened, about 3 to 4 minutes.
03 - Stir in the black beans, ground cumin, chili powder, smoked paprika, salt, and black pepper. Mix thoroughly to combine flavors.
04 - Pour the enchilada sauce and tomato sauce into the skillet. Stir until the mixture is evenly combined.
05 - Arrange half of the corn tortilla quarters evenly over the beef mixture. Sprinkle with half of both cheeses. Top with the remaining tortillas followed by the rest of the cheese.
06 - Lower the heat to low, cover the skillet, and simmer for 5 to 7 minutes until the dish is hot and the cheese is melted.
07 - If desired, place the skillet under the broiler for 2 to 3 minutes until the cheese is bubbly and golden brown on top.
08 - Remove from heat and top with green onions, cilantro, sour cream, and diced avocado as preferred. Serve immediately.
