Prepare the mixture: In a large mixing bowl, combine the drained tuna, breadcrumbs, egg, mayonnaise, green onions, jalapeño, cilantro, garlic powder, onion powder, black pepper, salt, and lemon juice.

Form the patties: Using your hands, shape the tuna mixture into small patties, about 2-3 inches in diameter. You can expect to yield about 6 to 8 patties, depending on how large you make them.

Warm the oil: In a spacious frying pan, heat the olive oil over medium heat. When the oil is hot, gently add the tuna patties to the skillet, ensuring there’s enough space between them.

Sauté the patties: Cook the patties for 3 to 4 minutes per side, until they are crispy and golden brown. Adjust the heat as necessary to prevent them from burning.

Plate the dish: Take the tuna cakes out of the skillet and transfer them to a plate lined with paper towels to absorb any excess oil. Enjoy the patties while warm, served alone or alongside a salad, rice, or a flavorful dipping sauce such as aioli or tartar sauce.
