Prick the potatoes with a fork, place on a microwaveable plate and microwave on high (700W) for 8-10 minutes or until tender. Stand for 2 minutes.
Meanwhile, heat the oil in a medium frying pan and gently fry the salmon, snow peas and Cajun seasoning for 5 minutes or until cooked throughout. Add creme fraiche and gently heat through.
Cut the potatoes in half or make a cross in the centre and divide the salmon between the two potatoes. Serve with fresh salad leaves or vegetables.
