Butternut Squash Pizza with Hazelnut Dough

Preheat oven, preferably convection, to 500 degrees. Drizzle squash with oil, and season with salt; toss.

Spread cornmeal on a baking sheet. Stretch dough into a 9 1/2-inch round; transfer to baking sheet. Drizzle dough with oil, and arrange squash on top, leaving a 1/2-inch border. Bake for 6 minutes (10 minutes if not using convection oven). Meanwhile toss sage with garlic, and drizzle with oil to coat. Sprinkle sage mixture over pizza. Bake until crust is golden brown and cooked through, 6 minutes more (10 minutes more if not using convection oven). Garnish with hazelnuts, and drizzle with oil.
