Mike,
If you want to keep it simple then just mix up a few herbs and or spices that compliment turkey. If you're not sure about Creole flavors, you can always buy a small container and taste it first. Traditional herbs for turkey include sage and thyme. Fresh herbs are usually preferred but using a dried rubbed sage and dried thyme make it easy to apply to the bird. A little salt and pepper and with those and you're good to go. You can also consider granulated onion and garlic to rub on with the pepper. I would recommend as many here do; and that is to salt the turkey first. Just pure salt and in the amount that you would salt a piece you would eat; nothing more. Then add your other herbs. This way, if you want to up the herb flavor you aren't throwing the salt way out of balance.
