Jumbo Shrimp in Diced Tomato, Onion, and Feta

I had a hankering last night for jumbo shrimp.  Yes I happen to have some available in my fridge, lucky me.  Years ago I made a version of this and it was far better from a Greek cookbook I have but couldn't find last night.  Anyway, saute some onion in a pan with some olive oil.  Once it's nice and soft add 1/2 a can of diced tomatoes with juice and let it simmer down.  Meanwhile add all your seasonings, salt, pepper, Greek seasonings, garlic.  Once it's reduced, add cooked jumbo prawns and finally nice hunks of feta cheese and let it melt.  Simply lovely.  Watched it during Bachelor Pad....interesting.
