Based on a Greek bean dish called Gigantes Plaki, this soup is really hearty and filling but still manages to taste a bit summery thanks to its Mediterranean ingredients – always welcome on a wintery walk. If you're eating it at home, serve it with warm sourdough bread for a really indulgent lunch.
The feta and olive ‘sprinkles’ are optional but they are really easy to knock up, and lift the whole thing to another level.
