Boil pasta, add olive oil and set aside and let cool. Once cool, add sliced onion. For the tuna, I drain the liquid before adding it to the pasta. Then season with mayonnaise, soy sauce, and black pepper. So easy, even your children will enjoy making this! If you don't like tuna you can make with tenderloin chicken strips.
