Teriyaki Sauce
I make a marinade that I absolutely love, and have used it for both chicken (wings, breasts, or whatever) and steak.
1/4 cup soy sauce
1/4 cup water
scoop (tablespoon-ish) minced garlic
1 tablespoon of lemon juice or vinegar
The longer you marinade, the more it soaks in... all day or overnight is best, in my opinion.
I know there are some carbs in soy sauce, but, in my opinion, what gets soaked into the meat is minimal (i.e., you're not going to be DRINKING the marinade to consume all the carbs that's in the soy sauce... )
