01 - In a large oven-proof skillet over medium-high heat, crumble and cook the ground beef until thoroughly browned. Drain excess fat if present.
02 - Add diced onion, minced garlic, and red bell pepper to the pan. Sauté for 3 to 4 minutes until vegetables are softened.
03 - Mix in the drained black beans, ground cumin, chili powder, smoked paprika, salt, and black pepper. Stir well to distribute seasonings evenly.
04 - Pour in the enchilada sauce and tomato sauce. Stir to combine all ingredients thoroughly.
05 - Arrange half of the quartered corn tortillas over the beef mixture. Sprinkle with half of both cheeses. Repeat layering with remaining tortillas and cheese.
06 - Reduce heat to low, cover the skillet, and simmer for 5 to 7 minutes until heated through and cheese is completely melted.
07 - If desired, place the skillet under a broiler for 2 to 3 minutes until the top is bubbly and golden brown.
08 - Top with green onions, cilantro, sour cream, or diced avocado as preferred. Serve hot.
