This is a simple salad to make that you may use as a lunch or at a cook-out. Years ago, when I was little, an aunt used to come to see us and bring a pasta and tuna salad to bring to the beach (on ice, of course). We would have a picnic and I remember the little shell pasta having tuna tucked inside. I thought that was great and I loved it; soooo cute. After I grew up and got married I continued to make this salad in the summer and still do. And each time it reminds me of the times at the beach and the little pieces of tuna tucked into the shell. I thought that my aunt was so smart thinking of shells to bring to the beach. It really doesn't take much to make a kid happy, huh?
