Pea Puree

[Vegetables]

1 medium onion

45g/1½oz butter

150ml/¼ pint white stock

450g/1lb frozen peas

salt and freshly ground black pepper

225g/8oz mashed potatoes

1. Chop onion finely and put it with the butter, stock and peas into a saucepan. Add a little salt and pepper. Cover and simmer until peas are tender.
