I needed to make about 25 tuna salad sandwiches, so a large batch was in order. I was handed two 4 pound cans, and shown a walk-in cooler filled with all sorts of produce and condiments. Tuna salad making definitely scales up and down, so this will work with a much larger or smaller amount as well. I figured I would stick with the basics of great tuna salad: solid white Albacore packed in water, salt and pepper, chopped celery and lots and lots of mayonnaise. Since I didn't perform the actual sandwich making part of the process, I can't say exactly how far this batch went, but it seemed likely there would be plenty, and I was able to snack to my tuna lovin' heart's content.
