Escarole is a bitter green that stands up to heat and is suitable for grilling, braising, or using in soups. In this salad, it’s broiled with radishes before being dressed in a sweet, garlicky dressing that cuts the bitterness. Escarole is high in folate (vitamin B9), important in red blood cell formation, and vitamin A, important in immune function and eye health. Like kale and other cruciferous vegetables, it’s also very high in vitamin K, which assists in blood clotting.
