Prep the Mixture. In a large bowl, combine drained tuna, breadcrumbs, egg, mayo, mustard, garlic powder, onion powder, salt, pepper, and herbs. Mix until well combined.
Shape the Patties. Use your hands or a scoop to form the mixture into 6 to 8 even-sized patties. Press firmly to ensure they hold their shape.
Pan-Fry Until Golden. Heat a bit of olive oil in a skillet over medium heat. Cook the patties for 3–4 minutes per side, or until golden and heated through.
Serve & Enjoy! Serve warm with your favorite dipping sauce, salad, or side.
