In a mixing bowl, combine the flaked salmon, bread crumbs, beaten egg, parsley, green onion, Dijon mustard, lemon juice, salt, and black pepper. Mix until well combined.

Shape the salmon mixture into small patties or croquettes, about 2 inches in diameter.

Heat the vegetable oil in a frying pan over medium heat. Once hot, carefully add the croquettes in batches, frying for about 3-4 minutes on each side or until golden brown.

Remove the croquettes from the pan and place them on a paper towel to drain excess oil. Serve warm with your favorite dipping sauce.
