Tunatastic Gourmet Tuna Sandwich

"My 8 year old daughter, who aspires to be a chef when she grows up, created this in the kitchen one day for her friends to eat. I was horrified as I watched her mix ingredients I thought should never go together. But her friends absolutely loved it. Needless to say, I had to try it myself and was astonished at the creation she had made. So I sat down with her and measured it out to perfection to create her very first master recipe! We love to make this from time to time with sandwich bread or crackers! Her friends always ask her to make it when they come over. Her name is Eternity, remember it, cause one day she will be the next Rachel Ray! P.S. The recipe calls for Basil Pesto. We buy the already made in a jar basil pesto from "Classico". We have not yet tried it with any other basil pesto recipe."
