Mashed sweet potatoes are a great way to get your kids to eat some healthy vegetables. To skin or not to skin, that is the question. Sweet potato skin has about three times the antioxidant levels as the rest of the vegetable. If you enjoy the taste of skin-on mashers, you're doing yourself a favor. But if you decide on no skin, you'll still be getting a good dose of vitamins, minerals and antioxidants.
Cut three large sweet potatoes into about 2-inch chunks (the smaller the chunk, the faster they'll cook) and drop them in boiling water. Cook until completely tender, about 15 to 20 minutes. Drain the water from the potatoes, and mash with milk, butter and a pinch of salt and pepper until reaching your desired consistency.
