My husbands family got this marinade recipe from the Norbest turkey farm. It was originally meant for their Turkey Tenders. We use it on any kind of poultry. It is very good grilled. We usually 1/2 the recipe for our use.
1 quart 7-up or gingeralle (I have used diet and didn't notice)
1 pint oil
1 pint soy sauce
1 Tbsp horseradish
1 tsp garlic powder
Marinate for 24 hours in a Ziploc. Yummy.
