Using a Mandolin, thinly sliced cabbage, red onion and bell peppers. Dice tomatoes, slice meats and cheeses and portion out other ingredients.
Combine ingredients to the hoagie sauce and whisk in a bowl until smooth. You will have more hoagie sauce then needed depending on the size of the cabbage. The dressing will last in the fridge up to a month.
In a large mixing bowl combine all the veggies, meats and cheeses then pour in about a 1/2 cup of the hoagie dressing. Toss to combine, add extra dressing as desired. Keep remaining dressing for dipping with veggies.
