I make my own burgers, similar to what some of you said. minced mixed with onion, bread crumbs, egg, spices...I keep it pretty standard normally, but once made some with little chopped up tomatos and cilantro which were nice.
Also make my own sausages. Always two badges. One flavor is more Italian with basil, oregano, etc., and the other one spicey with cilantro.
Chicken wings I marinade mostly with onions, garlic, honey, lemon, soy sauce, mustard, salt, pepper, and a bit of bbq sauce. My kids love it.
And my potato salad has no competition. Same as my deviled eggs, etc...
