Make a bbq sauce by combining the brown sugar, ketchup, vinegar, Worchestershire sauce, salt, pepper, mustard, and onion powder together in a large bowl.
Stir the chipped chopped ham in with the sauce.
Heat the ham and barbecue sauce on the stove in a large skillet or pan at medium heat until warmed through about 15-20 minutes.
Keep warm in a slow cooker until ready to serve.
Serve on Kaiser rolls.

Notes
You could skip heating the ham barbecue on the stove and go right to the slow cooker. It only needs to warm through and kept on warm after.
