With the first cool weather come thoughts of soup—warming, nutritious, tasty! In Tuscany, cannellini beans are a favorite, simmered along with garlic, a splash of olive oil, and a hint of rosemary. Beans are full of healthful fiber, protein, and potassium, in addition to iron and calcium, and are an easy way to prepare a one-pot meal. And at just 56¢ per serving, it's one of our cheapest dinners yet. Optional kale can be tossed in for the last few minutes of cooking for extra nutrients, and serve with crusty Italian bread and a wedge of cheese if you like.
