Heat oil in a large pan over medium-high heat and add onions, sautéing for 10 minutes until soft and golden brown.
Add wine, vinegar and sugar to onions, reduce heat to low and let simmer for 5 minutes until most of the liquid has been absorbed.
Remove from heat and season with salt and pepper.
Heat medium skillet over medium-high heat and brown sausage, crumbling with a spatula/spoon/fork.
Remove from heat.
Preheat oven to 375 degrees and pre-cook pizza dough for 10 minutes or until golden brown.
Once pizza dough is pre-cooked, remove and top with 3/4 of the cheese, sausage and onions and place back in the oven.
Broil for a couple minutes to create a crispy crust.
Top with remaining manchego and enjoy!
Recipe Notes
* Check the bottom of the crust before removing pizza… you may need to cook it for a few additional minutes on convection to get the air circulating and the bottom of the crust adequately cooked.
