In a large mixing bowl, combine the chopped salmon, breadcrumbs, beaten egg, mayonnaise, Dijon mustard, lemon juice, green onions, parsley, salt, and black pepper. Mix well until all ingredients are evenly distributed.
Form the mixture into 4 equal-sized patties.
Heat the olive oil in a skillet over medium heat. Cook the salmon patties for about 4-5 minutes on each side, or until golden brown and cooked through.
Serve the salmon burgers on buns with your favorite toppings and condiments.
