BARBECUED FILLETS
Combine the mushrooms, onion, and green pepper and sprinkle evenly over the meat. Roll up jelly roll fashion, starting from the long side. Cut into 1 1/2" wide slices. Wrap the edge of each slice with a strip of partially cooked bacon, securing with wooden picks. Freeze with a piece of waxed paper between each patty in a large freezer bag. Makes 5 burgers.
When thawed, grill over medium coals 8 minutes. Turn and grill 8 more minutes.
