Ingredients

• 1 large potato, peeled and cubed
• 4 (3 ounce) cans tuna, drained
• 1 egg
• 1/4 cup chopped onion
• 1 tablespoon Dijon mustard
• 1 tablespoon dry breadcrumbs, or as needed
• 1 1/2 teaspoons garlic powder
• 1 teaspoon Italian seasoning
• 1/4 teaspoon cayenne pepper
• salt and ground black pepper to taste
• 1 tablespoon olive oil

Instructions

1. Place the potato into a small pot and cover with salted water. Bring to a boil over high heat, then reduce heat to medium-low, cover, and simmer until tender, about 20 minutes. Drain and allow to steam dry for a minute or two, then mash the potato with a potato masher or fork in a large bowl.
2. Mix the tuna, egg, onion, Dijon mustard, bread crumbs, garlic powder, Italian seasoning, cayenne pepper, salt, and pepper into the mashed potato until well-blended. Divide the tuna mixture into 8 equal portions and shape into patties.
3. Heat the olive oil in a skillet over medium heat. Pan fry the tuna patties until browned and crisp, about 3 minutes on each side.
