I don't have much jambalaya making experience and I am not a big fan of spicy creole food. Nonetheless, I think this sounds really good. I love that it has shrimp!
I think I am going to add in some chicken or turkey sausage instead of ham. Some Food Network reviews also said it was a bit bland, so if you like your food spicy you may want to consider amping up the spice.
Happy Jambalaya Cooking!
