Fry the bacon in a pan until just cooked. Remove from heat and dice into 1/2-inch squares. Set aside. Heat the honey and pear slices in a flat pan over medium heat. When the honey begins to boil, bring the heat down to low and allow it to continue to cook for 15 minutes, stirring every few minutes. Then remove the pan from the heat and set aside.

Heat the onions and the olive oil in a large pan over medium heat until the onions soften and turn slightly transparent, about 10 minutes, stirring every couple minutes. Add the sugar, butter, and salt and stir. Lower the heat and allow to cook for about 30 minutes, stirring every 5 minutes. If the onions begin to crisp and dry out, add a tablespoon or two of water to keep them soft. Be prepared though, when you add the water the pan will hiss and spatter. The onions are finished caramelizing when they turn a rich deep golden brown. Set them aside.

Preheat the oven to 400 degrees Fahrenheit. Roll out the dough on a lightly floured surface to your desired thickness and shape. Transfer the dough to a baking pan. Evenly disperse the honeyed pear sauce over the dough, leaving a 3/4 inch border on the dough for the crust. Spread 3/4 of the blue cheese crumbles on top of the pear sauce, then spread the bacon and caramelized onions on top of the cheese, and then sprinkle the remaining blue cheese crumbles over the bacon and onions.

Place the pan in the oven and bake for 15 to 20 minutes, or until the crust begins to turn golden brown.
