- 4 ounces pepperoni, sliced

Step-by-Step Instructions: Making Your Italian Sub Squares

- Prepare the Rolls: Preheat oven to 350°F (175°C). Do not seperate rolls. Using a serrated knife, carefully slice the rolls horizontally, keeping the top and bottom connected as one piece.
- Layer the Ingredients: Spread half of the provolone cheese evenly over the bottom half of the rolls. Layer the ham, salami, pepperoni, and remaining provolone cheese on top. Sprinkle with Parmesan cheese.

- Prepare the Dressing: In a small bowl, whisk together the melted butter, Dijon mustard, Worcestershire sauce, Italian seasoning, and garlic powder.
- Drizzle and Bake: Drizzle the dressing evenly over the top of the fillings. Place the top half of the rolls back on.

- Bake: Cover with foil and bake for 15 minutes. Remove foil and bake for another 5-10 minutes, or until the cheese is melted and the rolls are golden brown.
- Slice and Serve: Let cool slightly before slicing into individual squares. Serve warm.

Tips & Tricks for the Best Italian Sub Squares
- Use high-quality ingredients: The better the ingredients, the better the taste!
- Don’t overbake: Overbaking can dry out the rolls.
- Adjust the dressing to your liking: Add a pinch of red pepper flakes for heat.
- Let it rest: Letting the squares rest for a few minutes before slicing helps the flavors meld together.
- Use softened butter: Softened butter mixes more easily in the dressing.
Variations: Make it Your Own!
- Vegetarian: Use roasted vegetables, mozzarella, and pesto.
- Turkey & Swiss: Substitute turkey for ham and Swiss cheese for provolone.
- Spicy: Add jalapeños or a dash of hot sauce to the dressing.
- Different Cheeses: Experiment with different types of cheese, such as mozzarella, cheddar, or pepper jack.
