This was a really good, yet simple salad. I thought the shell pasta was a perfect match with the shrimp. I usually put celery or green pepper into salads like this, but the scallions gave enough color, crunch and flavor that I didn't miss those. I did, however, think it needed some other herb or spice, like parsley or dill or tarragon to pick up the flavor a bit. I will add one of those next time. Thanx for posting!
