Heat the oil in a large saucepan, then add the onion and cook on a low heat for 5 minutes until soft but not browned.
Stir in the stock, cover and cook for a further 5 minutes.
Stir in the peas, bring it back to a simmer and cook for a further 5 minutes, or until the peas are cooked.
Puree the soup in a blender/liquidiser or with an immersion blender. Enjoy!
Recipe VariationsHerbs: try adding a tablespoon of fresh chopped mint or a tablespoon of fresh chopped basil, stirred in at the end before serving. Cream: To serve, swirl in a dollop of plain Greek yogurt, vegan yogurt, or cream. Onions: try swapping the onion for shallots. Chunky: You don't have to blend this soup. It's also nice served unblended with the peas and onions in the vegetable broth.
