Step 1

Preheat the oven to 350 degrees F. Add the red onion to a bowl, pour some cold water over it, and let it sit. This will take away some of the bitterness. Whisk the mayonnaise, red wine vinegar, oregano, red pepper, and garlic cloves. Add in the lettuce, onion, and pepperoncini, and give it a taste. Adjust the salt and pepper to taste.

Step 2

Slice the bread in half and add Calabrian chili paste to both sides of the bread. Add the cheese to one of the halves. Add the meats to the other half. Transfer to the oven to bake for about 5 minutes, until the cheese is melted and the meat is warmed. Add the salad on top of the meat, along with a few slices of tomato, fresh onion, and parmesan cheese.

Step 3

Slice in half and enjoy. #grindersandwich
