Flank Steak Marinade

We were first introduced to this delicious marinade several years ago when we first moved to San Diego. Andrea had invited us over for dinner (if I remember right it was Easter) and they made this marinade. We don't just use it on flank steak...although, it's definitely the best with flank steak...but it works for other beef cuts as well :)

1 ½ cup oil
1/3 cup lemon juice
¾ cup soy sauce
½ tsp parsley
¼ cup Worcestershire sauce
1 tsp pepper
¼ cup vinegar
1 tsp salt
2 TBL dry mustard
1 clove minced garlic

Pierce 3 flank stakes and marinate for 3 DAYS. (very important) Grill. Cut crosswise in thin slices and serve.

Can also marinate other beef steak cuts, but the key is the time (3 days...if you don't have time for 3 days, you must marinate for at least 6 hours) and cutting it crosswise.
