Tuna spread is made of a creamy mayonnaise and tuna mix. Its texture makes it easy to use as a dip for your fresh-cut veggies or crispy crackers. The protein-packed tuna makes this healthy spread an easy, nutritious snack or meal. Aside from protein, you will also get a generous dose of omega-3 fatty acids, vitamins B6 and 12, iron, magnesium, and potassium. You can use this tuna salad as a veggie dip, as a spread for a bagel, or dolloped onto a crispy lettuce salad.
