re: Good marinade for flank steak?

I really like the flavor this imparts:

London Broil Marinade

4 cloves Garlic, chopped
1/4 cup Red Wine Vinegar
1/4 cup Balsamic Vinegar
3 Tbs Lemon Juice
2 or 3 Tbs Dijon Mustard
2 Tbs Worcestershire Sauce
1.5 Tbs Soy Sauce
1 tsp Oregano
1 tsp Thyme
1 tsp Basil
Salt & Pepper to taste

1. Mix together all ingredients in small bowl. Pour over meat in ziploc bag or foodsaver bag. Marinate for at least 24 hours for best flavor.

2. You can either grill the meat, basting often with marinade, or you can broil it in the oven - "I broiled mine on high in a pyrex dish with the marinade for 10 minutes on each side and it came out perfect."

enough for a 2-3 pound piece of meat
