That's a good looking plate of food.
I like Zatarains but, I've been using more King Kooker these days. I like their seasoning and their boil/fry rigs are fantastic!

I'm with you there. I see folks having a picnic with mayo based slaw sitting in the sun for hours and think my goodness that must be awful. Vinegar based slaw for me thanks!
If it were me I'd be outside all day admiring those beauties! They look really nice. Man you'll be able to put out the food off those two! Spectacular!
