Portuguese-Style Rice with Kale and Plum Tomatoes

A staple on the Portuguese table, arroz de grelos customarily is made with spicy turnip greens (grelos), but in our version, we opted to use easier-to-find lacinato kale. Bunches of kale vary in size, so to make sure you purchase enough for this recipe, weigh the kale on the produce scale at the grocery store; you need 1 pound. Serve this simple yet remarkably flavorful one-pot dish as the center of a vegan or vegetarian meal, or offer it alongside almost any simply prepared meat, poultry or seafood.
