I used to watch that guy on TV growing up in Houma. When I got the "Frank Davis Cooks Cajun, Creole and Crescent City" cookbook, I picked up the beef and vegetable seasonings. They are pretty good. I can't remember where in BR I bought them. I want to say it was one of the Associated Grocers stores.
If you haven't checked out that cookbook, the Mardi Gras steak and potatoes is delicious. Third Recipe Down
