1. Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch casserole dish.

2. In a large skillet, cook the ground beef over medium-high heat until browned. Drain excess fat.

3. Add the diced onion and green bell pepper to the skillet and cook for 4–5 minutes until softened.

4. Stir in the diced tomatoes, tomato sauce, corn, green chilies (if using), garlic powder, onion powder, chili powder, cumin, salt, and pepper. Simmer for 5–7 minutes to thicken.

5. Pour the beef mixture into the prepared casserole dish and spread evenly.

6. In a bowl, combine biscuit mix and milk. Stir until just combined. Fold in half of the cheddar cheese.

7. Drop spoonfuls of the biscuit dough over the beef layer. Spread gently without covering entirely.

8. Sprinkle remaining cheese on top and dust with paprika if desired.

9. Bake uncovered for 25–30 minutes or until the biscuit topping is golden and cooked through.

10. Let rest 5–10 minutes before serving. Garnish with sour cream or fresh herbs if desired.
