In a large bowl, combine the salmon, onion, celery, parsley, breadcrumbs, garlic powder, onion powder, smoked paprika, salt, pepper, mayonnaise, and egg. Mix until everything is evenly combined.
Form the salmon mixture into 4 equal patties.
Heat the olive oil in a large skillet over medium-high heat. Add the patties to the skillet and cook for 4-5 minutes on each side, or until they are golden brown and cooked through.
To assemble the burgers, place a patty on the bottom bun. Top with lettuce, tomato, and red onion. Add the top bun and enjoy!
