Sauté bacon for 5 minutes on medium low heat then add wine and rosemary. Cover and braise on low heat for about 15-20 minutes. Remove cover and pull out rosemary stems (by this time most of the tiny leaves will have fallen off and bacon will be infused with rosemary flavor.) Continue to cook until wine has evaporated and bacon becomes deep golden brown. Drain bacon on paper toweling and set aside.

Preheat oven to 400°. Place pizza stone or upside down sheet pan on middle rack of oven.

Place pecans in a small baking pan with melted butter and sea salt. Bake for 6-8 minutes or until deep golden brown, stirring every 2 minutes. Remove from oven and set aside.

Combine sweet potatoes, olive oil, salt and pepper in a medium bowl. Place sweet potato mixture on a baking sheet or small pan coated with cooking spray. Bake on upper rack for 20 minutes or until sweet potatoes are tender and beginning to caramelize in spots. Remove from oven and set aside.

Increase oven temperature to 475˚F.

Roll or press out pizza dough on a lightly floured surface to approximately a 14" circle. Don't worry if the shape is not perfectly round. Place a piece of parchment paper, slightly larger than your dough on a pizza peel or large cutting board. (The parchment paper will make your transfer of the pizza to the oven infinitely easier.) Sprinkle parchment paper generously with cornmeal. Fold dough in quarters and place on parchment paper, then unfold. This is when you can reshape it a bit if it has stretched into an odd shape.

Slide pizza-topped parchment paper from pizza peel (or cutting board) onto heated pizza stone (or upside-down sheet pan). Bake for 8-12 minutes or until crust is golden and cheese is bubbling. Remove from oven by sliding pizza-topped parchment paper back onto cutting board. Carefully lift one edge of the pizza and pull out parchment paper.

Combine pesto with 1 tablespoon olive oil. With a teaspoon, dollop pesto mixture over pizza. Scatter with toasted pecans.
