I stumbled upon Maine shrimp salad for 7.99/lb. while doing an errand at my local Shaws. It contained mayonnaise and celery that were not overwhelming. I added a squirt of lemon and some salt, and the results were quite tasty.
I was quite surprised to find it, since I thought the season didn't begin until December, and Maine shrimp can be hard to find even at the height of the season.
