volunteers. It has Romaine Lettuce (I know about the recall, this lettuce I got today is coming out of Watsonville, CA) large, shrimp, celery, and the dressing has creamed horseradish, fresh lemon juice and one more ingredient I cannot recall. I do not use mayo based salad dressings, so my only thought is that it must be sour cream. Any one have a recipe like this or maybe knows what that ingredient I cannot recall might be?
