I use Zatarans red beans and rice in the box. Sooooo good. I add some type of smoked sauge to it every time. Sometimes even a low-fat turkey sausage when I'm trying to watch my fat intake. Maybe not so unique, but it's just sooooo good.
I also use the Zatarains. We usually throw little smokies in. Sometimes we cut up another type of sausage, but usually the smokies. ( I like to use the cheese filled ones). Then we top it with onions and cheese. I don't know if that's unique or not, but we like it!
