Did you know that salad really isn't a summer food? Yes, we can find tidy greens in the supermarket year round, but most lettuce varieties — as well as our beloved arugula — really don't like summer heat. Unless grown under inside or under cover, most greens bolt, wilt, fail to germinate, and basically pout all summer long until the cooler weather of early fall arrives. So the real stars of summer salads and sautés are found elsewhere. Enter Malabar spinach.
