This summer stew is based on the Greek dish fasolakia: green beans and potatoes cooked down with tomatoes and olive oil. The result is melt-in-the mouth tender beans and fudgy, tomatoey potatoes – delicious topped with feta and dill. This is best at room temperature and tastes better after a day’s marinating, making it the perfect prep-ahead dish for a barbecue. Discover more delicious summer salads and sides.
