My next recipe for Love Watercress is green goddess soup

Green Goddess Soup
Ingredients
2 white onions, sliced
1 clove of garlic, crushed
3 medium courgettes, grated
30g watercress, roughly chopped ( plus extra for serving )
15g parsley, leaves and stalks, finely chop the stalk and roughly chop the leaves
1.5L vegetable stock
150g sour cream
Salt
Pepper
100g feta
Method
Heat a saucepan over a medium heat and add the sliced onions. Fry until softened and then add the garlic, fry for a further 30 seconds and then add the grated courgette and fry until starting to soften. Add the watercress and parsley to the frying pan and cover with the stock. Bring to the boil and then simmer for 20 minutes. Pour the soup into a blender and blitz until smooth. Once blended put the soup back in the saucepan and add the sour cream and season with salt and pepper. Stir over a low heat until the sour cream has melted into the soup (if looking for a richer soup you could add double cream instead). Pour into serving bowls and top with crumbled feta.
