Heat large frying pan to medium high heat. While pan is heating up, cut tops and bottoms off of peppers. Remove the core and seeds and cut the pepper into 1 inch thick segments (you’ll be filling them so don’t make any other cuts).
Pour 1 Tbsp olive oil into the heated pan and add the beef. Cook beef for 3 minutes and mince the meat while it cooks.
Add taco seasoning, stir together and cook for 1 minute.
Add corn and beans to the beef, stir together. Lower the heat to medium and let cook for 3 more minutes.
Heat another pan to medium heat. Pour in 1 Tbsp of olive oil.
Place pepper segments in the pan and let cook for 2 minutes on one side.
Flip the peppers over and fill with the taco filling. Cover with desired amount of cheese and cover the pan with a lid.
Cook for 1 minute or until cheese melts. Carefully use a spatula to get completely underneath each pepper and serve.
