You can actually use pretty much any salad dressing as a marinade. We had a restaurant in our city when I was growing up (Bonanza, for anyone who cares) that used to have a dish on their menu called Catalina Chicken. My mom loved it and asked them one time what they used for a marinade. Their response...Catalina Dressing (Kraft makes a Catalina dressing, not sure about other brands). She said, "That's it???" Yep. That's it. During grilling season, we just toss a bunch of chicken in a zip top bag, dump on some Catalina, and maybe add a bit of garlic, salt, and pepper, though that isn't necessary at all, and then let them marinade for the day before grilling.
Our local Whole Foods has a number of options for chicken in marinades, one of which is Caesar (just marinated in Caesar dressing). Also at Whole Foods, you can buy Cindy's Kitchen, Rosemary and Roasted Garlic Vinagrette. We used it as a marinade a couple of weeks ago and it was soooo good. I do add a bit of salt and pepper to the bag along with the dressing to enhance the flavour, but again, it tastes great without if you are watching your sodium or prefer to season your food after it is cooked.
I also have a marinade recipe that I use for steak tips, but that could be used for chicken as well. It would likely be especially good with thighs over breasts. Mix equal parts of Wishbone Creamy Italian dressing, Wishbone Zesty Italian dressing, and BBQ sauce, marinate, then grill.
