In a mixing bowl, flake salmon with a fork and stir in green pepper, onion, mayonnaise, lemon juice and cayenne. Add the lightly beaten egg, parsley, paprika, garlic powder and 1/2 of the bread crumbs. Using clean hands, roll the mixture, meatball style into 7-8 balls.
In a dish, spread the remaining bread crumbs. Roll the balls in the bread crumbs, flattening into cakes 1/2" to 3/4" thick. Fry cakes until golden brown in a skillet with 1-2 tablespoons light olive oil or peanut oil with 1-2 tablespoons butter melted in.
In a lightly buttered skillet over medium heat, fry cakes until golden brown on both sides.
Serve with Lemon Sauce, tartar sauce, or seafood cocktail sauce, garnished with lemon wedges.
