I got this recipe from my sister-in-law. We do a lot of grilling, and this is the best marinade we've tried. It's great for shish kebabs (use sirloin tip or top), thick porkchops, and chicken breasts!
Mix:
1/2 c. salad oil
1/2 c. LaChoy soy sauce
2 T. white vinegar
1 T. minced onions
1/2 tsp. ground ginger
1/2 tsp. garlic powder
Marinate meat in refrigerator at least overnight. When making kebabs, marinate veggies an hour before cooking.
Enjoy! :)
