How to Make Baked Italian Grinder Subs
Step 1 – Prep the rolls
Preheat the oven. Slice the rolls on the side without cutting all the way through. Brush Italian dressing on the inside of each roll.

Step 2 – Layer the fillings
Layer with pepperoni, folded turkey slices, provolone cheese, red onion, sweet and hot salad peppers, and a sprinkle of salt, pepper, and oregano.

Step 2 – Make garlic butter
In a microwave-safe bowl, melt butter with garlic salt. Brush the mixture generously over the tops of the rolls.

Step 3 – Bake and Serve
Place the sandwiches in the oven and bake in the preheated oven until the cheese is melted and the tops are golden. Remove from oven, let cool, and enjoy!
