Preheat the oven to 375°F (190°C).

Cut the tops off the bell peppers and remove the seeds.

In a skillet, heat olive oil over medium heat. Add ground beef and cook until browned.

Stir in taco seasoning, black beans, corn, and salsa. Cook for an additional 5 minutes.

Remove from heat and mix in half of the shredded cheese.

Stuff each bell pepper with the beef mixture.

Place the stuffed peppers in a baking dish and cover with foil.

Bake in the preheated oven for 25 minutes.

Remove the foil, sprinkle remaining cheese on top, and bake for an additional 5 minutes until cheese is melted.

Let cool for a few minutes before serving.
