This easy, plant-based Sweet Potato Mac ’n Cheese is made with delicious, nutritious ingredients and spotlights roasted sweet potato. Sweet potatoes are among the healthiest common whole-food sources of potassium, which every cell in our body requires to function. Fewer than 2 percent of Americans achieve even the recommended minimum intake of potassium, due primarily to inadequate intake of plant foods. We need 4,700 mg of potassium a day. Feeling creative? Add even more vegetables to this dish and top it with additional salt-free spices, to taste. If you’re looking to add more beans to your diet, use a legume-based pasta or add some cooked tofu or tempeh.
