Braised little gems and peas with summer herbs and shallots

Melt the butter in a deep frying pan over a low-medium heat. Add the shallots and cook for 5 minutes, until softened. Stir in the lettuce hearts and cook for a further minute. Add the stock and peas to the pan, cover with a lid and simmer very gently for 10-12 minutes, until the lettuce is tender. Season, stir in the herbs and finish with a spoonful of crème fraîche.
