French bean salad

Serves 2
Prep time 25 minutes
Cooking time 5 minutes
This dressing makes a healthy change to a regular oil and vinegar one. Any variety of green bean would work well here, like runner or dwarf but you could equally use broad beans or peas.
Ingredients:
150g French beans, trimmed
2 spring onions, sliced
6 radish, sliced
3tbsp natural yoghurt
zest of ½ lemon
2 sprigs dill, chopped
lettuce to serve
