Coconut curried mussel soup

So, never have I had mussels.  I have 2 brother in laws that are chefs, I want to make like a thai curried mussel soup and they felt it would be a  good combination.  So tonight is going to be a huge surprise.  I am hoping (after going to my fish monger) and buying 6 pounds of mussels that I like them.  I am also going to serve my avocado pomegranate spinach salad.  Looking forward to tonight's dinner.
