For those of you who haven't noticed it's hot, and I for one am not in the slightest bit interested in all the traditional nonsense of Christmas. Take a large salmon, ask the fishmonger to remove the head, fins and scales, bake it in the oven and serve with new potatoes with chopped mint and a drizzle of olive oil, a crisp green salad with sliced avocado and a cool refreshing mango and coriander salsa. If you want to be more decadent decorate fresh prawns around the outside - what could be nicer, and how much better knowing it's good for you.
