Place catfish fillets in an electric skillet with sides. Add broth, and cook on high until fish flakes easily, about 6 minutes. Drain fish.
Flake cooked fish into large bowl, and add Miracle Whip. Add egg and diced vegetables, and stir. Add cracker crumbs and seasonings; then mix well.
Form into patties, and fry in hot oil, turning as needed, until desired browning is achieved on both sides. Serve with tartar sauce or rémoulade.
