In a large bowl, combine the flaked salmon, breadcrumbs, green onions, mayonnaise, egg, Dijon mustard, garlic powder, lemon juice, salt, and pepper. Mix until well combined.

Form the mixture into patties, about 2-3 inches in diameter.

Heat olive oil in a skillet over medium heat. Once hot, add the salmon patties to the skillet.

Cook for about 4-5 minutes on each side, or until golden brown and crispy.

Remove from skillet and place on a paper towel to drain any excess oil. Serve warm.
