Carbonnade is the French term for meat grilled over coals. This recipe was on a 'free recipe' 3 X 5 card I picked up at a United Supermarket, I think it was in Quanah, Texas on US-287 Between Ft Worth and Amarillo. I found the card while cleaning out my old pickup,getting ready to sell it, it had been behind the drivers seat for years. I finally gave it a try, It ain't half bad. See what you think. IT DOES MARINATE OVERNIGHT.
