Preheat Oven: Preheat your oven to 375°F (190°C).

Cook Beef: In a skillet over medium heat, brown the ground beef until fully cooked. Drain any excess fat, then mix in the taco seasoning according to package directions.

Layer Ingredients:

• Spread a thin layer of refried beans over the bottom of a 9×13 inch baking dish.

• Layer four lasagna noodles over the beans.

• Top with half of the cooked beef, half the diced tomatoes, half the corn, and one-third of the shredded cheese.

Repeat Layers:

• Add another layer of noodles and repeat the beef, tomatoes, corn, and another third of the cheese.

Top Layer:

• Add the final noodle layer. Spread sour cream evenly over the top, then sprinkle with remaining cheese and chopped red onion.

Bake: Cover the dish with aluminum foil and bake for 25 minutes. Remove the foil and bake an additional 10 minutes, or until the cheese is bubbly and golden.

Garnish: Garnish with fresh cilantro before serving.
