Wash spring onions and cut into 2cm slices

Heat olive oil in a deep pot and add he spring onions. Fry until soft but not brown

Add stock powder and water and cover with the lid of the pot until it begins to boil

Remove the lid of the pot and simmer for 10 minutes

Remove pot from stove and blend the soup using a stick blender until desired consistency is achieved (I like a chunky texture)

Add salt and pepper to taste

Top with feta cheese
