You can substitute tofu “bamboo," first soaking it in hot water until soft, or tofu “skins” cut into ribbon-like pieces—a very common addition to Chinese summer salads. And you can season the sauce more highly, if you like, with garlic, cilantro, or ground roasted Sichuan peppercorns. Once you get to know these flavorsome ingredients, you can make a wide variety of summer dishes with the vegetables available in your region.
