Meatball Submarine Sandwich.  The submarine bun is not gluten free but a gluten free option is available.  Meatballs are made from ground beef and pork with seasoning and parmesean cheese.  They are egg and gluten free.  Mozzerella cheese and romano cheese are layered into the sandwhich.  The mozzerella cheese is lactose free but the parmesean and romano are not.  It comes foil wrapped for easy oven warming.  For microwave just unwrap and warm on a plate.
