Paulkys' recipe is close to my moms and how I do it...
can of tuna
1 hard boiled egg diced
1/4 cup chopped celery
1/2 cup chopped white onion
1/4 cup sweet pickle relish
HELLMANS mayonaise...if it ain't Hellmans, it ain't mayonaise (gigging you Paulky...lol)
mix up, toast some white bread, put on about 1/2 inch of the tuna salad, some sliced fresh slice jalapenos, get some potato chips and a large glass of iced tea and have at it..
