Thaw bread dough on lightly greased cookie sheets. Fry bacon until lightly browned but not crisp, add diced onion, fry until onion is translucent. Drain off and reserve drippings. Let cool. Mix egg into cooled bacon and onion mixture. With floured knife, cut thawed bread dough into approximately 2 inch slices. Roll out dough slices on lightly floured board; shape into squares or rectangles.

Place about 2 heaping tablespoons bacon mixture in middle, spread thinly and roll up, seal ends, seam down. Place about 2 inches apart on a lightly greased cookie sheet. Let rise in warm place until doubled, about 1 1/2 to 2 hours. Bake at 400 degrees for about 45 minutes or until golden brown. Brush tops lightly with bacon drippings immediately. Let cool on brown paper bag.
