What you will need:
In a large skillet, cook beef, onions and garlic over medium heat until the meat is no longer pink; drain. Stir in the ketchup, barbecue sauce, brown sugar, vinegar, mustard, Italian seasoning, onion powder and pepper. Bring to a boil. Reduce heat; simmer, uncovered, for 20 minutes.
Serve about 1/2 cup meat mixture on each bun.
Serve on buns.
I use potatoe chips as a side, but have also made potatoe salad
