In a bowl, combine the egg, cottage cheese, oil, honey and salt. Dissolve yeast in warm water; add to egg mixture. Add wheat germ and 1-1/2 cups flour. Mix on medium speed for 3 minutes. Add chives and enough remaining flour to form a soft dough.
Turn onto a floured surface; knead until smooth and elastic, about 10 minutes. Place in a greased bowl, turning once to grease top. Cover and let rise in warm place until doubled, about 1 hour.
Punch dough down; roll out to 3/4-in. thickness. Cut with a 3-in. round cutter. Place on greased baking sheets. Cover and let rise until doubled, about 45 minutes.
Brush tops with egg and sprinkle with onion. Bake at 350° for 15-20 minutes or until the rolls are golden brown.
