re: What are some good healthy chicken marinades?

I don't really measure the spices, but I always do a combo of:

Olive oil
garlic powder
onion powder
pepper
smoked paprika (a good bit)
chili powder
Knorr powdered chicken base

You can add salt if you want but the chicken base usually has enough salt in it.

Mix in ziplock bag, toss in chicken and coat well- I use tenderloin or cut breasts in strips if going for low fat (thighs work well too), let marinate for at least 30 mins, throw on grill.
