Tuna Spread, tuna on toast
We grew up eating tuna salad sandwiches or as we called them, “Tuna fish sandwiches”.    Mom made tuna spread with canned tuna, chopped pickles either dill or sweet, plenty of chopped hard boiled eggs and enough mayonnaise to hold everything together.   Sometimes mom would add a leaf or two of lettuce on top of the tuna sandwich spread.   Those sandwiches with a side of chips and we were in heaven, it was a perfect summer time lunch and was one of our favorites.

We weren’t introduced to Tuna Melts until we were adults.  And not sure if Tuna Melt sandwiches were just not popular in our area of the woods or if my mother just didn’t like them.
