Follow these simple steps to create your amazing Cheeseburger Subs:

1. Preheat Oven: Preheat your oven to 350°F (175°C).
2. Cook Beef: In a large skillet over medium heat, brown the ground beef. Break it apart as it cooks.
3. Season Beef: Once the beef is cooked through, drain any excess fat. Stir in garlic powder, onion powder, paprika, salt, and pepper. Mix well.
4. Prepare Rolls: While the beef is cooking, slice the sub rolls in half lengthwise without cutting all the way through.
5. Add Beef to Rolls: Place the cooked beef mixture into each sub roll, filling them generously.
6. Add Cheese: Top each filled roll with a slice of cheese. Place the subs on a baking sheet.
7. Bake Subs: Bake in the preheated oven for about 5-7 minutes, or until the cheese is melted and bubbly.
8. Assemble Toppings: While the subs are baking, prepare the toppings—slice the tomato and wash the lettuce.
9. Load Up Subs: Once the subs are out of the oven, add shredded lettuce, tomato slices, and pickles to each.
10. Condiments: Finish with your choice of ketchup and mustard before closing the sub rolls.
