Step-by-Step Instructions

1. Prepare the Bread

  3. Add cheese slices, ensuring full coverage of the beef.
  4. Top with optional banana peppers and shredded lettuce for extra flavor and crunch.

4. Bake the Sandwiches

  1. Place the top half of the bread over the layered fillings.

  3. Wrap the assembled sandwiches tightly in aluminum foil.
  4. Place on a baking sheet and bake for 15-20 minutes, or until the cheese is melted and the sandwiches are heated through.
