Baked italian sub sandwiches

Ingredients

4 sub rolls (6 inches each)
8 oz provolone cheese, sliced
4 oz salami, sliced
4 oz pepperoni, sliced
4 oz ham, sliced
1 cup romaine lettuce, shredded
1 large tomato, sliced
2 tbsp olive oil
Instructions

Preheat the oven to 400°F (200°C) and prepare a baking dish with nonstick spray.
Slice each sub roll lengthwise without cutting all the way through; lay them open in the baking dish.
Layer salami, pepperoni, and ham inside each roll followed by provolone cheese.
Top with shredded lettuce and tomato slices; sprinkle with oregano if desired.
Drizzle olive oil over each sandwich for added crispiness.
Bake for 10-12 minutes until cheese is melted and bread is golden brown.
