reminds me of the sandwiches we’d have on those little pedestal grills at the state park growing up. Mom would start the charcoal, lay out some aluminum foil and start cooking onions and green peppers. Add italian hot sausage links and sear the outside. Before the sausages wet fully cooked she’d slice them down the side and open them like a book and lay the open side down on the foil, sear to good brown fully cooking the sausage, then add barbecue sauce and mix in the onions in peppers and cook the works until the sauce was thickened. Slap down a sliced hard roll on top for a bit to warm up right in some sauce on a cleared area on the foil. Then making sure there was some sauce on the roll halves lay down thenopened sausage and some saucy peppers and onions. Bbq sauce on italian sausage sounds bizarre but it works!
