I make a mean meatball sandwich. I make the meatballs using hot Italian sausage, and either beef or veal. Add some spices, Parmesan, and bake till done. Then cook in a spicy tomato sauce. Split open a long French baguette. Add meatballs, more Parm, and mozzarella and bake till the cheese is bubbly. My question - has anyone made a sandwich using a different sauce other than tomato based? Any suggestions and/or recipes would be much appreciated. Thank you much!
