In a large bowl, dissolve yeast in warm water. Add the sugar, egg, oil, salt and 3 cups all-purpose flour. Beat on medium speed for 3 minutes. Stir in whole wheat flour and enough remaining all-purpose flour to make a soft dough.
Turn out onto a lightly floured surface. Knead until smooth and elastic, about 6 to 8 minutes. Place in a greased bowl, turning once to grease top. Cover and let rise until doubled or cover and refrigerate overnight.
Punch dough down and form into dinner-size rolls. Place on greased baking sheets for plain rolls or knots, or in greased muffin tins for cloverleaf rolls. Cover and let rise until doubled, about 1 hour for dough prepared the same day or 1-2 hours for refrigerated dough.
Bake at 375° for 10-12 minutes or until light golden brown. Serve warm. If desired, dough may be kept up to 4 days in the refrigerator. Punch down daily.Yield: 24 servings.
