Unfortunately I do my tailgating from my house in fla but when I do go to the fins game I usually make the following depending on crowd:
Jalapeno's stuffed with cream cheese and wrapped in bacon
Wings are always a must
Marinated skirt steak to make gyros, add fresh pitas, tatziki, lettuce, tomato, onion and cucumber
after the game I pull out the Italian sub: Large french or Italian bread loaf, Baked ham, genoa salami, cappicola and proscuitto. add let, tom, onion and oil n vin etc.
I make a variation of this with spicy sausage and a can of hot rotel tomatoes and peppers. nice and spicy and you cant stop eating it. cheap and easy
