Preheat the oven to 350°F (175°C).

Combine the ground beef, crushed tortilla chips, diced onion, bell pepper, whisked eggs, Rotel tomatoes, drained corn, taco seasoning, and 1 cup of shredded cheese in a large mixing bowl.

Transfer the mixture into a lined 9x5-inch loaf pan, shaping it into a loaf.

Bake in the preheated oven for 50 minutes. Add taco sauce and remaining cheese if desired before proceeding.

Finish baking for an additional 10-15 minutes until the internal temperature reaches 160°F (71°C).

Rest the meatloaf for 10 minutes before slicing.
