Iceberg and peas

I recently shopped at a supermarket and picked up lambs lettuce (whilst it was available) not remembering that I bought an Iceberg lettuce the previous day at the local fruit shop and that evening my neighbour brought round... a lettuce. There's only so many salads one can endure.

Lettuce and Pea Soup with Mint

1 tbs butter
125g sliced leeks
400ml stock (vegetable or chicken)
400ml water
500g shredded iceburg lettuce
125g peas (fresh or frozen)
50g chopped fresh herbs
¼ tsp cayenne pepper

A dollop of yogurt, crème fraîche or sour cream wouldn't go amiss.

Melt butter in a saucepan over medium-high heat. Add leeks, stirring until softened. Add stock, water, peas, herbs, pepper and lettuce. Bring to a boil. Reduce the heat and simmer for 10 minutes.

Place the soup in a whizzer with chopped mint leaves and purée until smooth.
