I'm always tempted to buy a flank steak or London Broil for marinating and grilling. But I never seem to get them as tender or as flavorful as I would like. I'm aware this type of cut will probably never melt in the mouth - and I understand you must slice it a certain way. But I'm hoping y'all can offer your favorite recipes and methods of preparing them. (Will also appreciate slow-cooker ones as well.)....Thanks!
