To save time, look for precooked eggs, such as Eggland's Best, in the dairy section of the supermarket.
Combine all ingredients, then spread between the slices of bread.
*To hard-cook eggs, cover them with 1 in. water and bring water to a boil. Remove pot from heat and cover it with a lid; let stand 12 minutes. Drain and peel eggs.
