1/2 cup vegetable or peanut oil
1/2 cup ketchup
1/4 cup red wine
1 tablespoon chopped parsley
3 tablespoons wine or balsamic vinegar
1 teaspoon garlic powder or 4 cloves garlic, minced
1/2 teaspoon each salt and pepper
Optional Additions: 1/2 teaspoon each celery salt, or fresh ginger, minced, 2 teaspoons soy sauce, chives and shallots. If you would like to add 1/2 teaspoon dry mustard, omit ginger and soy sauce. Note: 1 1/2 teaspoons of Good Seasons Italian Dressing (dry and unmixed) may be substituted for the salt, pepper, and garlic powder for a quick marinade. A spicier version can be made by adding 1/4-1/2 teaspoon of hot red pepper flakes, cayenne or hot sauce.
Combine all ingredients. If you have a blender available, all the hand chopping can be avoided - just toss in the garlic, parsley, etc. and add the liquids and seasonings, then blend.
In a Ziploc bag, marinate steak for 4 to 8 hours (overnight for best results). Cook on grill until desired degree of doneness is reached. Serve with baked potato and a garden salad.
