You may think of citrus fruits as the vitamin C powerhouses, but potatoes, including the skins, are good sources of this immunity-boosting vitamin. Potato skins also contain B vitamins, calcium and other nutrients. Potato skins are also rich in phytochemicals.
Rub the outside of each potato with olive or canola oil, about 1/2 teaspoon per potato. Sprinkle a little kosher or sea salt on potato skins. Place potatoes on a cookie sheet and bake until tender, approximately 1 hour. Cut each potato in half lengthwise. Scoop out the potato and place in a medium mixing bowl. Leave a thin layer of potato behind to prevent skins from tearing. Add 1/4 teaspoon paprika, black pepper, salt to taste, yogurt, milk, 1/2 cup cheese and green onion to potato.
