I love tuna salad and I love macaroni salad, so I came up with this to blend them both, but in a healthy way! If you are not worried about cholestrol, feel free to use both the yolk and whites. Since I leave out the egg yolks, I splurge with real mayonnaise, but if you like low fat mayo....go for it. Once you have the eggs cooked and macaroni cooked and cooled, it is a snap to throw together.
