Brussels Sprouts, Sweet Potato, and Balsamic Pizza

Instructions

1. Preheat oven to 400°F. Line a baking sheet with foil. Arrange Brussels sprouts and onion on the prepared baking sheet. Brush with 1 tablespoon of the milk. Roast 10 minutes or until vegetables are nearly tender, brushing lightly with milk if vegetables start to look dry. Remove vegetables from baking sheet and sprinkle baking sheet with cornmeal.
2. Meanwhile, in a large saucepan combine sweet potato and enough water to cover. Bring to boiling; reduce heat. Simmer, covered, 10 to 12 minutes or until tender. Drain and return to saucepan. Mash sweet potato until smooth. Stir in 2 tablespoons of the milk and the rosemary. Season with salt and pepper.
3. On a lightly floured surface, roll pizza dough into a 12-inch circle. Transfer to the prepared baking sheet and brush with 1 teaspoon of the milk. Bake 8 minutes. Spread with mashed sweet potato; top with roasted Brussels sprouts and onion. Bake 8 to 10 minutes more or until crust is golden and crisp.
4. For balsamic glaze, in a small saucepan bring vinegar to boiling; reduce heat. Simmer, uncovered, 6 to 8 minutes or until thickened to a syrup consistency. Drizzle pizza with balsamic glaze and, if desired, sprinkle with additional rosemary.
