Cheesy Minute/Sandwich Steak Casserole from Food.com: Super cheesy, stick to your ribs, definitely NOT a diet dish. Fairly quick to make...kids LOVE it. My b/f came up with this one night when all we had in the freezer were some minute/sandwich steaks. I have 30 minutes for prep time but I've seen him toss this together in half that time. The kids don't like chopped green peppers but I think they would be great in this dish. Also great for covered dish suppers.
¼ c. balsamic vinegar 1 T. Worcestershire sauce 2 tsp. dark brown sugar 1 garlic clove, minced 1 lb. flank steak salt and pepper Combine first four ingredients in a large ziplock bag. Add steak, turn to coat; marinate for 30 minutes at room temperature. Grill until desired doneness. Let stand, covered loosely with foil for 10 minutes, before cutting in thin strips against the grain.
