In the bowl of a bread machine, combine all ingredients minus egg white in the order listed.
Select the dough cycle on machine and let run.
Once cycle is complete, turn out dough onto a floured surface and divide into 4 equal parts.
Roll each part into a ball and place on a greased cookie sheet.
Let dough balls rise for 30 minutes. While rising, preheat oven to 400.
Brush tops of dough balls with egg white wash and bake for 15-20 minutes, or until golden brown.
To serve, cut top off each and hollow out being sure to leave the bottom and sides in tact.
