For the prawn and salmon cakes:
1) Add the oil to a large frying pan over a medium heat. Stir in the onion and pepper and saute until soft. Add the prawns and cook until the prawns turn pink.
2) Allow to cool, then add the remaining ingredients and mix gently. Do not over mix. Form the mixture into 225g balls, then flatten them into patties.
3) Heat the griddle to high. Griddle the cakes on both sides until heated through. Transfer to a serving platter and serve with the red pepper sauce.
