In large mixer bowl, combine 1.5 c. flour, yeast, 1 T. sugar and 1 t. salt; mix well. Add water and oil to flour mixture. Blend at low speed until moistened; beat 3 minutes at medium speed. By hand, gradually stir in enough remaining flour to make a firm dough. Knead on floured surface 5 to 8 minutes, adding flour as needed. Place in greased bowl, turning to grease top. Cover; let rise in warm place about 40 minutes (20 minutes for Quick Rise yeast).

Prepare onion topping. In small skillet, saute onion in butter until soft. Stir in one third t. sugar and 0.125 t. salt.

Punch down dough. On lightly floured surface, shape dough into a ball. Place on greased cookie sheet. Flatten to a 25 cm circle. With table knife, cut a circle in dough about 3 cm from edge, cutting almost through to cookie sheet. Prick center with a fork. Spread Onion Topping over the pricked dough. Cover; let rise in warm place about 30 minutes (15 minutes for Quick Rise). Bake at 375 deg. for 25 to 30 minutes until golden brown.

Variation. Omit Onion Topping. Instead of pricking top, cut a criss-cross design with a sharp knife. Brush bread with an egg glaze made by combining 1 egg yolk and 1 T. milk or water. Sprinkle with sesame seed if desired.
