Preheat oven to 400 degrees. Rinse and pat the salmon dry. Then, place it on a parchment-lined baking sheet and season with half teaspoon of salt and pepper. Roast until cooked through, about 15 minutes. Allow to cool 5 minutes. Once cooled, using a fork, flake or separate the salmon into small pieces. Place salmon in a large bowl. Add onions, Ritz cracker crumbs, parsley, mayonnaise, mustard, egg, lemon juice & seasoning. Season with 1 teaspoon of salt and pepper and mix gently. Using a measuring spoon, take 2 tablespoons of the mix, form it into a ball and place on a parchment-lined baking sheet. Once all mix has been used, bake at 400 degrees for about 15-20 minutes, just until they start to crisp and become golden.
Combine all ingredients in a small mixing bowl whisk thoroughly. Add salt and pepper to taste.
