I say if you are trying to impress the girl, do something out of the ordinary. Like
this. And then sear a few scallops to throw on top and drizzle a little truffle oil over it. It will taste amazing and even if she doesn't like scallops, at least you will impress her with your perceived creativity. Besides, you can always serve the orzo without the scallops if you find she is a veggie. Or do vegetarians still eat seafood? I get confused on that.
