Garlic Butter Rolls
Preheat your oven to 'low broil'.
Mix together the melted butter, garlic paste, fresh herbs, red pepper flakes, and parmesan cheese in a small bowl.
Place the the bread rolls onto a baking sheet, then generously brush the tops with the garlic butter. Toast in the preheated oven for up to 5 minutes.
Make the Grinder Salad
In a large mixing bowl, toss together the mayonnaise, red wine vinegar, olive oil, Italian seasoning, garlic powder, parmesan cheese, garlic paste, iceberg lettuce, pepperoncini peppers, fresh parsley, and red onion slices until everything is well combined.
Let marinate while you build the rest of the sandwich.
Build the Grinder Sandwich
Open the toasted rolls and smear the rest of the butter on the inside of the bread, then top with your meats and cheeses.
Toast the sandwich again for a few minutes under the low broiler until the cheese melts, then top the sandwich with slices of tomato, avocado (if using), and the grinder salad.
Fold the top of the bread over the sandwich, give it a squish, and enjoy!
