Start by washing and slicing your vegetables. Rinse the romaine lettuce and dry it thoroughly, then shred it into bite-sized pieces.

Slice the cherry tomatoes, red onion, and banana peppers. Set aside in a large bowl.

In a small bowl, whisk together the olive oil, red wine vinegar, oregano, salt, and pepper.

Add the salami, pepperoni, capicola, provolone cheese, olives, and the prepared dressing to the bowl of vegetables.

Toss everything together gently until all the ingredients are well coated.

Slice your hoagie roll open lengthwise. Optionally, toast the insides for a crispier texture.

Layer a generous amount of the mixed salad onto the bottom half of the roll.

Top with the other half of the roll to complete your sandwich.

Cut the Italian Grinder Salad Sandwich in half and serve immediately, alongside chips or a light soup.
