Well I asked the HD when I started 5 years ago and he said, “you can cook whatever you want just so it is on the grill of the cart.” Codes vary by state, wilddogs and I am servsafe certfd.  6oz sirloin grilled to order, topped w/provolone, pepps n onions on a nice hearth baked roll cost $2.32, sell for $6. They sold well enough to do again. Thanks CCinNJ, mikejames, joedog, jcheese for your input.
