Step 1

Preheat the oven to 425 degrees F (220 degrees C).

Step 2

Heat olive oil in a skillet over medium-high heat. Add onion and red bell pepper; saute until softened, 5 to 7 minutes. Add ground beef, garlic, chili powder, cayenne pepper, salt, and black pepper. Cook and stir until beef is browned and crumbly, 5 to 7 minutes.

Step 3

Mix corn into the beef mixture and toss to defrost, about 3 minutes. Drain and discard fat. Add about 1/4 of the shredded Mexican cheese blend and mix well. Pour meat sauce into a 9x13-inch casserole dish. Cover meat with a thin layer of salsa.

Step 4

Combine cornmeal, salt, and baking soda in a large bowl. Add milk and eggs; stir until well blended. Pour cornmeal mixture on top of salsa layer and top with remaining shredded Mexican cheese blend.

Step 5

Bake in the preheated oven until browned on top, about 30 minutes.
