Chop onion and green pepper into 1-2" chunks.
Combine beef, egg, Worcestershire, chips, and seasonings in a bowl, being careful not to over compact.
Roll meat in-between your hands to create golf ball sized meatballs.
Place green pepper, onions, and meatballs on skewers, alternating each.
Set on grill, rotating occasionally, adding sauce as the meatballs near the end of cooking.
If using the oven, slather in BBQ sauce and place under the broiler, rotating and adding more sauce until cooked through. Turn frequently to prevent burning.
