There are a variety of ways to customize this easy meal. I like to mix tuna with light mayonnaise and relish. Some people enjoy tuna with mustard, paprika, hard boiled egg, or a cheese. Feel free to prepare the tuna to your own liking, and add spices to the mix as your heart desires. The vegetables and tuna have plenty of taste that you shouldn't need or desire a sauce or dressing, so steer clear of these sugary, salty, and fatty condiments.
