TikTok Grinder Salad Sandwich

Step 1
Preheat the oven to 400 degrees F (200 degrees C).

Step 2
Place ciabatta cut side-up on a baking sheet and layer one piece of the bread with slices of provolone and the other with mozzarella.

Step 3
Bake on the top rack of the preheated oven until the cheese melts, 3 to 4 minutes. Remove from the oven and increase the temperature to broil.

Step 4
Layer both sides of the sandwich with folded slices of ham, then alternate between the two sides with a layer of salami, coppa ham, prosciutto, and pepperoni. Broil in the oven until the meats crisp up, 2 to 3 minutes.

Step 5
Stir mayonnaise, minced garlic, red wine vinegar, oregano, red pepper flakes, pepperoncini peppers, salt, and pepper together in a large bowl. Add the lettuce, red onion, and black olives, and toss to combine.

Step 6
Thinly slice the tomato and salt on each side.

Step 7
On one side of the sandwich, layer the tomato slices. Pile a large portion of the lettuce salad on top, then top with grated Parmesan cheese. Carefully fold the two bread slices together to form the sandwich. Cut into 4 triangular portions and serve immediately.
