Butter lettuce, pea and feta salad

Instructions

1 Fill a bowl with cold water and ice. Bring a pot of water to a rapid boil then add all peas and cook for 1 minute. Drain and plunge into ice-cold water to cool right down to help peas retain their bright-green colour and crispness.

2 Arrange lettuce leaves on serving platter. Top with peas. Crumble over feta and croutons (if using).

3 Whisk together yoghurt and mayonnaise until smooth and creamy then drizzle over salad just before serving.
