In a mixing bowl, dissolve yeast in warm water. Add oil and sugar and let stand for 5 minutes. Stir in the egg and salt.

Add the whole wheat flour and 1 cup of the bread flour. Gradually add the last cup of flour until a soft dough forms (you may not use all the flour).

Turn onto a floured surface and knead until smooth and elastic, 3-5 minutes.

Divide the dough into 8-10 equal pieces (depending on the size of bun you want) and shape each into a ball.

Place 3 inches apart on lightly greased baking sheets. Cover and let rise for 15-20 minutes.

Preheat oven to 425 degrees. Bake buns for 7-10 minutes or until golden brown. Remove from pans to wire rack to cool.
