I've made this a few times now and it's always quick and surprisingly satisfying for a reduced-fat entree. I keep frozen cooked shrimp on hand as a staple for a last-minute but gourmet dinner. They defrost in a matter of minutes, so I don't take them out of my freezer until I'm ready to start cooking. I put the shrimp in a colander, run tepid water over them for a minute or so, and after they sit about five minutes, I can pull the tail shell off, and they're ready to heat up! Serve over pasta or rice.
