Crumble the curry leaves into a small frying pan on a medium heat. Add a big lug of oil, and the fenugreek and mustard seeds. Fry until the mustard seeds start to pop, then stir in the mango chutney. Remove from the heat and leave to cool. Puff up the poppadoms by microwaving for a minute or two. Peel and grate the carrots on a large board, then chop and add the cucumber, spring onions, radishes, lettuce, tomatoes and chilli (deseed it first), mixing and chopping as you go. Pick over the herb leaves and give it a good final chop. Pour over the toasted spices, add a squeeze of lemon juice, a pinch of sea salt and mix and chop it all up with your knife. If it’s too dry, add extra oil and lemon juice. Serve sprinkled with crunched-up poppadoms, and extra dollops of mango chutney, if you fancy.
