I normally add the following:
1 tablespoon Mrs. Dash Chipotle Seasoning (my fave)
or
1 tablespoon granulated garlic (or garlic powder) and 1 tablespoon black pepper (close 2nd fave) - this is better than the garlic pepper version sold by Owens BBQ
or
1 tablespoon of granulated garlic
To any of the above, I sometimes add a bit of cayenne pepper to spice it up a bit...usually no more than a teaspoon.
Every now and again I come across a seasoning that I like and I will add 1 tablespoon to original, mesquite or hickory flavor packs...beware of seasonings with salt though.
