I'm cooking for a group with numerous food allergies on Sunday and need a taco seasoning that is gluten (wheat), dairy, and egg free. McCormicks (my normal standby) has whey (milk) and I think I'm going to have to make my own. What all goes in? Cumin, I'm sure of, but what else? I figured seasoned ground beef and/or chicken, corn tortillas and flour ones for those that can have, and numerous toppings will make a feast for all. Thanks!
