1 1/2 c. salad oil
3/4 c. soy sauce
1/4 c. Worcestershire sauce
2 tbsp. dry mustard
2 1/4 tsp. salt
1 1/4 tsp. parsley flakes
1 tbsp. black pepper
1/2 c. wine vinegar
1 clove garlic
1/3 c. lemon juice

Put all the ingredients in a blender for 40 seconds. Keeps well in the refrigerator for several months. This is a good marinade for Swiss steak and/or beef cooked on the grill.
