Preheat the oven to 190C/170C (fan)/Gas 5
Place the ginger, garlic, cumin, curry leaves and oil in a bowl and mix. Smear all over the chicken and place in a lidded ovenproof dish.
Add the remaining spices and pour in enough water to come a third of the way up the chicken.
Cook the chicken for 1 hour, then remove the lid and cook for a further 15-30 minutes, or until the chicken is cooked through.
Meanwhile, for the green chutney, place all the ingredients except for the yoghurt in a blender and blend until smooth. Stir the blended herb mix in to the yoghurt.
Remove the chicken from the dish and strain the sauce in to a small pan. Add a little of the green chutney to the sauce and cook for 2-3 minutes.
Meanwhile cut the chicken in to 8 portions and return to the sauce, season with salt and freshly ground black pepper. Keep warm. (Simmer gently to reduce the sauce if necessary.)
For the salad, bring a large saucepan of salted water to the boil. Blanch the French beans, broad beans and peas. Drain and place in a large glass bowl. Add the fresh herbs and onion and toss together. Dress with a the olive oil, lemon juice and salt and pepper.
Put the chicken and sauce in a serving bowl and serve with the salad and chutney.
