Let’s jump to Bitter Greens. This category includes varieties that can stand up during cooking but are also tender enough for raw salads. Some examples of bitter greens include Belgian endive, frisee, arugula, escarole, watercress, and radicchio. Chicories are often sold but as baby greens because of a strong bitter flavor that develops with age. While all of these greens can be used in salads, Belgian endive, radicchio, and some others hold up to grilling, braising, and roasting. How’s that for a twist on a regular salad?
