Heat an oven to 400 degrees.
Slice the banana peppers in half lengthwise and core them out. Set them onto a large baking sheet.
Heat the oil in a medium pan and add the chopped steak. Season with garlic, paprika, salt and pepper. Cook about 5 minutes, or until the beef/steak is cooked to your liking.
Spoon the seasoned beef mixture into the peppers, then top each with shredded cheese.
Bake for 15 minutes. Alternatively, you can grill the stuffed banana peppers for 15 minutes, or broil them for 6-7 minutes, until the cheeses are nice and melty.
Remove from heat and set onto serving plates.
Top with chopped green onion, spicy chili flakes and hot sauce, if desired.
