I tried this last night. They were great. I love scallops. I might try mixing in some crab and/or minced shrimp and then broil it with some cheese on top. I find stuffed shells to be a fun way of serving pasta too.
These were not bad, but I felt like they were lacking something, and the celery was a bit overpowering for my taste. I loved how this recipe was very healthy, but next time I will tweak some things to make it suit my taste better.
