I like a salmon salad like my mother use to make. Mix good canned salmon with chopped boiled potatoes, chopped boiled eggs, a bit of pickle, mayo, mustard and seasoning. Chill and then mound it on a plate covered with lettuce leaves and decorate the top with sliced tomatoes, sliced cucumbers and whatever else sliced veggie looks appealing.
I ate this a lot growing up and it's so cool and summery, and yet it's quite filling.
