Preheat oven to 450 and grease baking sheet. Heat oil in large skillet over medium-high heat. Add onion and celery and cook, stirring, until softened, about 3 minutes. Stir in parsley and remove from heat. Place beans in a large bowl and mash into a smooth consistency. Add salmon (including canned bones and skin) and mash in with the beans. Add eggs and mustard and mix well. Add onion mixture and pepper and mix well. Shape the mixture into 8 patties, about 2 ½ inches wide and place on cookie sheet. Bake until firm and slightly browned, about 20 minutes (watch to check for burning and may need to turn down oven temperature) Serve with Creamy Dill Sauce and lemon wedges.
