First, slice your onion into thin slices. Melt butter in a bot or skillet when you finish with your slicing. Then add your onions and a bit of salt – let this cook for about 20 minutes, making sure not to burn the onions.
Then preheat your oven to 350 degrees Fahrenheit.
Combine ground turkey, Worcestershire sauce, 2 tablespoons of BBQ sauce, bread crumbs, pepper to taste, cheese, and onions in a large bowl.
Then take your 1/4 cup of BBQ, spread it over the top, and bake for about 20 minutes.
