Servings4 to 5 sandwiches
MAKE THE GARLIC AND HERB BUTTER
To a small bowl, add the melted butter, parsley, garlic, parmesan, black pepper, and oregano. Mix together and set aside.
PREPARE THE GRINDER SALAD
To a bowl, add water, ice, and the sliced red onion. Let it soak for at least 20 minutes to make it less bitter and more sweet. Drain.
Make the dressing in a small bowl by combining mayo, vinegar, garlic, parsley, mustard, parmesan, salt, black pepper, red pepper flakes, and Italian seasoning until smooth.
Add the lettuce, red onion, pepperoncinis, and the dressing to a large bowl and toss together. Taste and adjust anything to your liking.
PREPARE THE SANDWICH
Preheat oven to 350°F.
Brush the top of the bread with the garlic butter. Place cheese on the bottom of the bread and place it all on a baking tray and pop in the oven for 6 to 8 minutes just until the bread is toasted and the cheese is melted.
Once out of the oven, assemble with the deli meats on top of the cheese, then tomatoes, avocado if using, and lots of grinder salad. Add the bread on top, press down, and cut in half to enjoy!
