Method
- Thinly slice the leek. Drain the beans, rinse with water, then drain again.
- Heat 2 Tbsp of oil in a heavy based saucepan. Add the leek and a pinch of salt then cook on a low heat until tender. This will take about 8-10 minutes.
- Meanwhile mix the mustards with the vinegar, sugar and the remaining oil. Finely chop the parsley.
- When the leek has softened, add the beans and heat through. Take it off the heat, season to taste and stir in the parsley and the dressing.
- Serve warm.
