The secret to good tuna salad is to add something crunchy (celery, water chestnut, firm relish), something sweet (sweet relish, pinch of sugar), hard boiled egg yolk or diced whole hard boiled egg, and a small amount of breadcrumbs or crushed crackers to absorb excess moisture, with crackers being slightly tastier due to added sodium but breadcrumbs being preferred if you need to reduce sodium. You can also substitute canned salmon or similar for the tuna if mercury and pollutants are a cause for concern. And of course, a dollop of real mayonnaise, not artificially sweetened, hydrogenated and whipped vegetable byproduct.
