Plaki is a Greek method of cooking fish with vegetables. I first had this at a little neighborhood Greek restaurant here in my hometown. It was just around the corner from where I worked, so it was a popular lunch spot. Occasionally we were lucky enough to find this on their lunch specials menu....Lucky us! I recommend using a firm white fish....I use amberjack, grouper, or snapper. If you cut all the bloody pieces out of the fillet, you won't get a fishy taste. The fresher the fish the better! Prep time does not include the soaking/marinating time for frozen fish.
