The only thing I use London Broil for is for meat to make sandwiches. I either have the butcher slice it very thin, or I do it myself. Then you saute the meat for a very short amount of time (in olive oil or butter.) I like to serve it in warmed pita bread with grilled onions and mushrooms, plus a slice of tomato and maybe a small amount of mayonnaise for flavor. I’ve never had success broiling one (and I’m a pretty good cook...IMHO.)
London Broil makes the most awesome JERKY you’ve ever tasted,Besides wild game!
It is tough and chewy, without alot of marbling.
It really does make a nice sammich though, so does Tri-Tip, and my favorite...Chuck Roast.
