Tuna cranberry salad

The lady in front of me at Whole Foods bought this salad. The sign said tuna, cranberries, mayonnaise. Sounded simple enough, I thought I could do better at home. I wondered why they shredded the tuna to smithereens. What, do they have something against chunks?  And of course at home we have handmade mayonnaise, which is a whole 'nuther ball game. Enhanced here with celery and tomato and green onion. I could have kept right on enhancing, cucumber, olives, Parmigiano, curries, etc., but the Whole Foods version seemed simplicity itself, and it sure looked good. I used craisins.
