Whole-Wheat Spaghetti with Kale, Poached Eggs, and Toasted Breadcrumbs
Tuscan kale, sometimes labeled cavalo nero or lacinato or black kale, has dark leaves that are richly flavored. If you can't find Tuscan kale, you can use regular curly kale. Or try Swiss chard instead and cut the cooking time for the greens in half.
