The potatoes are a Paula Deen recipe that I thought I'd share with you .. I promise, your family will adore you, too.
I've used this teriyaki marinade for so long, I don't recall where I found it. Anyway:
Blend together: 2 tbsp garlic powder, 2 tbsp ginger, 1/2 cup brown sugar, 1 cup soy sauce, 1 cup pineapple juice, and 1/2 cup saki (I've never used the saki when I make this). Divide in half. Use half for marinade (2 hours) and put 1/2 in saucepan and heat. Thicken with cornstarch and use for sauce while grilling. Oh, and use fresh chicken breasts (so much better than frozen).
ENJOY!
