Kerala Style Mussel Stir-fry (Nadan Kallummakkaya Stir-fry)

This is Kerala style mussel stir-fry which could be served as an appetizer or as a side dish. I used the New Zealand green shell mussel which is available in half shells in the frozen section of the grocery stores here. After defrosting, the flesh can be easily removed from the shell using a sharp knife.
