Heat the oil in a large non-stick wok. Add the sweet potato and fry for 5 mins, stirring frequently until it starts to soften. If it starts to brown too quickly, put a lid on the pan. Add the carrot, courgette, onion, cumin and ginger, then cook over a high heat, stirring frequently, until the veg is tender and a little charred. Stir in the seeds towards the end so they cook for a couple of mins. Remove from the heat and add the lentils, bouillon powder, lemon zest, mint and parsley.

Meanwhile, stir the tahini with the garlic, yogurt and 1 tbsp water to make a dressing. Spoon the lentil salad into bowls and top with the dressing and paprika, if using. If you're following our Healthy Diet Plan, save two portions stored in containers and chill until ready to eat.
