This tuna burger recipe is a great way to switch up your burger game and is packed with protein and omega-3s. Using a food processor to chop the tuna ensures that the meat is finely chopped and results in a tender and flavorful burger. Mix in some breadcrumbs, egg, and herbs to the tuna and form into patties. Grill or pan-fry the patties until cooked through and serve on a toasted bun with a wasabi mayo sauce.
