Beef with sweet potato and grape

This is one of our special panini pies, which we only offer around holidays or other remarkable occasions. While combination of  sweet potato, grapes, olives and grpund beaf might appear unusual,  these  ingredients perfectly compliment each other. The idea for this recipie came after a trip to Italy, where we learned about a traditional Italian dish of sweet potato, grapes, and sausage cooked to celebrate the end of harvest.
