I was a clutz in the kitchen but one of the first dishes I made for my husband was butter garlic shrimp and pasta. It's really easy, you just chop up some garlic, green scallions and a few tiny bits of onion and toss them with a bar of butter in a skillet. Once the butter is melted just toss your shrimp in and cook for a few minutes. I served mine over fettucine but you can use whatever pasta you like. It was really good and made him "extra happy" in a way shellfish does to some people.
You can serve this with wine to make it extra special.
