The one I use All the time is 1/2c Olive oil, 1/4c worchestershire sauce, 6T soy sauce, 1/4c minced garlic, 2Tsalt, 1T pepper, 3T steak seasoning ( I use McCormicks Montreal Steak Seasoning) 3T A-1 Steak sauce.
Combine all together. Prick steaks with a fork, pour marinade on top of them and marinate for 2-24 hours.
So Fantastic! If I am not marinating them for too long I will also throw shrimp in any left over marinade and grill them alongside the steak. but don't marinate the shrimp any more than an hour, after that the marinade is too overpowering and the shrimp dont taste as good.
