SAUCE: In a small bowl, combine all the ingredients for the sauce. Stir and season with salt and pepper to taste. Refrigerate until ready to use.
SAUTE VEGGIES: In a medium skillet heat 1 tablespoon of olive oil over medium heat. Add the minced shallots, red bell peppers, and celery and cook for 3-5 minutes, keeping a close eye and stirring frequently. You want to just soften the veggies. Remove to a small plate or bowl, let cool to room temperature.
PULSE: Add the salmon to a food processor and pulse 2-3 times or until the salmon is well chopped and slightly sticky.
SHAPE: Remove the salmon to a medium bowl, stir in the cooled shallot mixture, parsley, capers, garlic, lemon juice, mayo, panko, seafood seasoning, cayenne, ½ teaspoon of salt, and ¼ teaspoon of black pepper. Combine until the mixture is evenly mixed. Divide the mixture into 6 patties. Place 2 tablespoons panko on a plate and place the patties on top. Sprinkle with another tablespoon of panko and press the patties gently.
COOK: Place a 12-inch skillet on the stovetop. Heat 2 tablespoons of oil over medium-high heat. Fry the salmon patties, flipping once after 3-5 minutes. The patties should be golden and crispy on the outside and cooked to your preference on the inside. Feel for firmness if you prefer a fully cooked patty.
