Blend together:

1 1/2 c. oil
3/4 c. soy sauce
1/4 c. Worcestershire sauce
2 tbsp. mustard
2 1/4 tsp. salt
1 tbsp. ground black pepper
1/2 c. wine vinegar
1 1/2 tbsp. parsley
4 cloves garlic, crushed
1/2 c. fresh lemon juice
Basil, oregano, tarragon, chervil, marjoram - a matter of preference

Blend together and use to marinate chicken, pork, beef, lamb - it does everything. I frequently double the recipe and keep it in a jar in the refrigerator during the summer so that I'm always prepared. Marinate meat 4 hours if you can plan that far in advance.
