Place sweet potato in a microwave-safe dish and microwave on high, turning halfway, for 6 minutes or until cooked through. If still firm, continue cooking for 1 minute intervals until just cooked. Cut lengthways into eighths. Heat oil in a frypan over high heat. In batches, fry, turning halfway, for 10-12 minutes until crisp. Remove and drain on paper towel. Meanwhile, toast sesame seeds in a dry frypan over medium-low heat, tossing frequently, for 3-4 minutes until white seeds are golden. Add remaining seeds and toast for 1-2 minutes until fragrant. Using a mortar and pestle, crush salt and chilli flakes. Combine with toasted seeds and roughly crush. Combine the yoghurt and lemon in a bowl. Set aside. Toss the sweet potato with seeds. Serve with lemon yoghurt.
