Mayonaise is usually the go-to dressing for a tuna salad, but if you want to give this dish a sweet, tangy zing, Thousand Island is the dressing you need.
Thousand Island will add dimension to your classic tuna salad while keeping it light and flavorful. You can either make it the main dressing or combine it with mayo.
Alternatively, you can make Thousand Island dressing from scratch by combining a base of mayonnaise, ketchup, relish, and an acid such as vinegar or lemon juice.
