This soup freezes well, the carrots give the soup a lovely sweetness, so it's great for kids. Good for part of the 5-a-day! It is quite a filling soup, so you could serve it for lunch as a snack meal with cheese and fruit afterwardsThere's nothing like a bowl of soup to warm you up in winter. This healthy pea and watercress soup with leeks and fresh mint is quick and easy to make as well.
