The combination of legumes and bitter greens like escarole is common in southern Italy. Escarole is a bitter lettuce that looks a little bit like frisée but with wider, tougher leaves. It’s high in vitamin A and a good source of iron and potassium. This recipe is adapted from one in “Cucina Rustica,” by Evan Kleiman and Viana La Place. If you can't find escarole, you can substitute any hearty green.
