Instructions:
Brown the meat: In a large skillet, cook the ground beef with the diced onion until browned and crumbly.
Add seasoning and filling: Stir in corn, black beans, diced tomatoes, and taco seasoning. Let simmer for about 5 minutes.
Layer it up: Grease a baking dish and spread a layer of crushed tortilla chips at the bottom. Add the beef mixture on top.
Cream & cheese: Evenly spread the sour cream over the meat layer, then sprinkle with cheese.
Bake: Preheat oven to 350°F (180°C) and bake for 20–25 minutes until the cheese is melted and golden.
Serve: Garnish with fresh jalapeños, cilantro, or an extra dollop of sour cream.
