We make tuna burgers with smashed avocado and tomato a lot at our house. I love the recipe so much that I included it in my book, Expect the Best, Your Guide to Healthy Eating Before, During, and After Pregnancy.
If you’re looking for an affordable, meatless meal, or you want a break from regular hamburgers, give these burgers a try.
Canned tuna helps you include seafood at least twice a week
Experts suggest that adults eat at least two fish meals weekly, and that pregnant and breastfeeding women consume two to three meals a week. However, you don’t need to be pregnant, breastfeeding, or trying to conceive to enjoy the benefits of these burgers!
My burgers are made with canned tuna, an inexpensive, convenient source of several nutrients, including protein, iodine, and omega-3 fats necessary for an adult’s heart health, and for a baby’s brain development and vision.

Use an empty tuna can to form the burgers so that they are uniform in size and fit on the buns or English muffins.
Pro Tip
Make a double batch of this recipe and freeze half. They are easy to reheat for a quick lunch or dinner.

Wrap cooked, cooled tuna burgers well and date the package. They will last for several months in the freezer. Reheat in the microwave and make the avocado/tomato topping just before serving.
