On a large cutting board, dice up the meats and cheese and transfer to a mixing bowl
Dice up the lettuce, tomato, red onion, peppers and optional olives
Add to mixing bowl- or you can do all chopping of meats and veggies at once
Mix together mayo, spicy mustard, Italian seasoning, salt, and pepper and combine with meat and veggies.
Make the vinegar and oil dressing by combining in a small bowl or bottle. We use a small squirt bottle like in restaurants to make it easy to apply to the sandwich.
Cut roll in half; some people remove some of the bread “flesh” so there more room for the mixture and a few less carbs. Broil for a few minutes; optional- spread the inside with mayo before broiling.
Top with salt and pepper to taste. Drizzle with the oil and vinegar mix.
