Boil the water and add the peas. If you are using fresh peas, cook it only for 2 minutes and if you use frozen peas cook it for 4 minutes or until tender.
Move it to the blender, add ginger, wasabi paste, salt, and pepper. Blend it well until the soup is creamy and light. If it is to thick for your liking just pour in additional hot water and check the seasoning.
Place in a bowl and garnish with chili slices and parsley.
