This refreshing salad combines the peppery bite of escarole with the delicate, curly texture of frisée. The addition of halved Kalamata olives provides a salty, briny contrast that elevates the simple greens. It is a light, crisp dish that pairs wonderfully with grilled fish or chicken, or stands alone as a healthy lunch option. The preparation is quick and straightforward, making it an ideal choice for busy weeknights or summer gatherings. The bitter notes of the greens balance the richness of the olives, creating a harmonious flavor profile that is both satisfying and refreshing. Serve immediately after tossing to maintain the crispness of the vegetables.
