Kana's Tuna Salad

"This is one of those recipes I've made so many times I don't even measure anymore. The mixture of Mayo/Ranch and a squirt of ballpark mustard is a trick I picked up from a local deli many years ago and gives it a nice zest. FYI - I'm not a huge fan of sweet relish or sweet tuna salad, this is a more tart, zesty version."
