Bring 1-2 litres of salt water (1 teaspoon salt per litre) to the boil. Cook the frozen peas for about 2 minutes. Drain and rinse with cold water. Clean, wash and halve the fennel and cut out the stalk.
Cut the fennel into thin strips. Cut dates in half. Mix peas, fennel and dates.
Wash coriander and shake dry, pluck off leaves. Finely puree the yoghurt and the coriander leaves, season with salt and 1⁄2-1 teaspoon cardamom. Approx. 1⁄4 Mix the yoghurt with the oil and the salad and leave to stand for approx. 20 minutes.
Dilute the remaining yoghurt with 600 ml cold water, season again with salt and pour into glasses. Arrange salad, serve with lassi. Naan bread tastes good with it.
