Mix salmon, panko, parsley, eggs, green onions, seafood seasoning, black pepper, garlic powder, Worcestershire sauce, Parmesan cheese, Dijon mustard, and creamy salad dressing together in a large bowl; divide and shape into eight patties.
Heat enough olive oil in a large skillet to cover the cooking surface over medium heat. Fry salmon patties in batches until browned, 5 to 7 minutes per side. Repeat with more olive oil, as needed.
