Preheat oven to 190C and dry the fish on kitchen paper. Brush a non-stick baking tray with a little of the oil and sit the fish fillets on the brushed area. In a small non-stick frying pan, fry the de-seeded and chopped yellow pepper over medium heat for 10 minutes until softened and slightly tinged gold, then add the peeled, chopped garlic and stir for a minute. Add the tomatoes (no juice), pesto, saffron and paprika and stir for 2 minutes, then stir in the olive slices and chopped parsley, plus seasoning to taste. Cook for a further minute then spoon the mixture onto the tops of the fish fillets. Bake for 12 minutes or until fish is just cooked through and topping is bubbling.
