Heat oven to 375 degrees F. Pat and stretch dough into 14x6-inch rustic rectangle on baking sheet sprayed with cooking spray; brush with oil.
Top with 1 cup cheese and half the onions, leaving 4 (3-inch) areas of dough untopped. (Eggs will be added here.) Crack eggs, 1 at a time, into small bowl, then slip onto dough. Top dough with tomatoes, bacon, remaining cheese and onions, being careful to avoid topping the eggs.
Bake 23 to 25 min. or until crust is golden brown and eggs are done.
