Preheat the oven to 425℉.
In a large oven-safe skillet over medium-high heat, add the ground beef to the skillet. Cook for 6-8 minutes or until browned, breaking up the ground beef with a spatula.
Add onions and green peppers and cook for 4-5 minutes or until they become soft.
Add garlic, tomato sauce, ketchup, brown sugar, mustard, Worcestershire sauce, black pepper, salt, onion powder, and paprika. Stir until combined and simmer uncovered, stirring occasionally for 6-8 minutes or until the sauce thickens.
Stir in 1 cup of cheese into the sloppy joe mixture. Then, sprinkle the remaining cheese over the top.
Top with the tater tots and bake for 30-35 minutes or until the tater tots reach your desired crispiness.
Server while hot and enjoy!
