Answer: mostly, yes.
Stubbs has a few variety of BBQ sauces. All of them appear to be gluten free (that’s a plus), and only 3 are non-vegan (honey): Smokey Mesquite & Honey Pecan — who’d have guessed?? They contain honey. Two of their rubs are not vegan, either. The Burger rub contains natural beef and bacon flavor, and the Herbal Mustard contains cheese.
I’d suggest grabbing some Stubbs Spicy and applying it liberally to tofu. Nothing is better than BBQ tofu.
