Place the potato wedges onto a baking tray and drizzle with olive oil. Sprinkle over the paprika and season with salt and pepper. Bake in the oven at 200°C for 20-25 minutes. Meanwhile, pan-fry the salmon on both sides in a hot pan with a little olive oil. Transfer to a baking dish, pop in the cherry tomatoes and continue to bake in the oven for 8 minutes. In the same pan sauté the prawns in a knob of garlic butter, splash in the wine and simmer to evaporate. Finish with a good pinch of fresh parsley. Next, slice the leeks and sauté in salted butter until soft. Add in the cream and Parmesan and cook gently till thickened. To serve, place the potatoes crossed in the middle of 2 plates and spoon over the creamed leeks. Place the salmon on top, arrange the cherry tomatoes around the plate and serve.
