Step 1

Scrub potatoes and cut in half. Peel parsnips and cut into 2-inch pieces. In a large saucepan cook potatoes and parsnips, covered, in enough boiling water to cover about 20 minutes or until potatoes and parsnips are tender; drain.

Step 2

Mash potatoes and parsnips with a potato masher or beat with an electric mixer on low speed. Add butter and pepper. Gradually beat in enough milk to make mixture light and fluffy. Stir in cheese. Divide evenly among six serving plates.
