Cook the frozen peas in boiling salted water for about 3 minutes. Drain and rinse with cold water. Cut avocados in half lengthwise and remove the core. Remove the flesh from the skin and cut roughly. Mash the peas in a bowl.
Wash the coriander, pluck off the leaves and chop. Stir lime juice into the cream.
Season to taste with salt and pepper. Goes well with hearty farmhouse bread.
