What do you normally cook down games and how long do you tailgate for?
For the next Eagles home game I plan on making chicken or veal cutlet sandwiches Italiano style (sharp provolone, broccoli rabe, long hots or roasted red peppers) and maybe some pasta fagioli. Chili is always good and can be made day before and reheated. I've done roast pork sandwiches (roast pork 2 days in advance, refridge overnight slice thin next day reheat in au jus down game top same as cutlets).
A good app is chorizo crostini, grill chorizo slice thin. Toast baguette slices lightly on grill; top with cooked chorizo, roasted red peppers, queso fresco (mex cheese) and avocado crema (blend 1 avocado, 1/2 cup sour cream, 2 tblsp lime juice and zest, cilantro and salt to taste). You can do same app Italian style: hot sausage, roasted peppers, roasted or sun dried tomato and mozzarella.
