I searched high and low for a Greek recipe for shrimp that included all the basics- tomatoes, garlic, oregano and of course, feta- and I couldn't find anything, so I took a couple recipes and tweaked them to my family's taste, and voila! This has been a hit since the first time I made it... it's full of flavor, rich but not too heavy! You can play around with the amounts given for any ingredient to satisfy your taste, but any way you make it, it turns out fabulous! We usually serve this as an appetizer with baguette to soak up the sauce... delicious!!!
