Use ground turkey breast and jazzed it up with some steak sauce and Worcestershire sauce.
I also finely minced an onion and mixed it in, then added about 1/4 cup bread crumbs.
I portioned the meat out so that each burger had 2 patties.
On the bottom patty I put some shredded pepper-jack cheese and a spoonful of the stuffing mixture I made (carmelized red onions with red peppers and fresh garlic that I did in a saute pan before putting the burgers together).
The burgers were grilled and then topped with a very thin slice of pepper-jack cheese.
Our veggies were new potatoes with mushrooms and red onions that had been marinated in olive oil, szechuan sauce, garlic, fresh black pepper and red wine.
