knob of butter or splash of olive oil bunch spring onions, chopped
3 smallish courgettes, chopped
200g frozen peas
850ml vegetable stock
85g bag trimmed watercress
Large handful of mint
2 rounded tbsp. Greek yoghurt, plus extra to serve.
Heat the oil or butter in a large saucepan, add the spring onions and courgettes and stir well. Cover and cook for 3 minutes, then add the peas and stock. Bring to the boil, then cover and simmer gently for 4 minutes.
Turn off the heat, stir in the mint and watercress and watch them wilt. Now puree it all until very smooth, preferably with a hand-held blender in the pan. Add the yoghurt halfway through blending, and serve drizzled with a little extra yoghurt.
