Combine Fresh Ingredients: Start by adding the finely chopped iceberg lettuce, thinly sliced red onion, chopped banana peppers, grape tomatoes, turkey slices, turkey pepperoni, turkey meat, provolone cheese, and grated parmesan cheese into a large mixing bowl.
Prepare the Dressing: In a small bowl or jar, combine mayonnaise with apple cider vinegar, banana pepper juice, garlic powder, dried oregano, and salt until smooth and creamy.
Season the Dressing: Taste your dressing mixture and season it with black pepper according to your preference.
Toss It All Together: Pour the dressing over your salad mixture in the large bowl and gently toss everything together until all ingredients are well-coated with that creamy goodness.
Serve and Enjoy: Once everything is mixed nicely, serve your Italian Grinder Salad immediately or allow it to chill in the fridge for a bit before enjoying it.
