Roasted Vegetable-Chicken Sausage Pizza

Preheat oven to 450°F. Line a 15x10-inch baking pan with foil. In a large bowl toss mushrooms and onion with 2 tsp. of the oil; sprinkle with salt. Transfer to prepared baking pan. Roast 5 minutes.

In same bowl toss sweet peppers and asparagus with 2 tsp. of the oil. Add pepper mixture and sausage to baking pan. Roast 15 minutes more or until peppers and asparagus are crisp-tender and starting to brown, stirring once. Carefully transfer foil with vegetables to a wire rack.

When pan is cool, brush with remaining 3 tsp. oil and sprinkle with cornmeal. On a lightly floured surface, roll dough into a 14x9-inch rectangle. Transfer to prepared baking pan; press edges into sides of pan. Bake 5 minutes (dough may puff). Remove from oven.

Carefully spread dough with dried tomatoes. Top with roasted vegetables, cheese, and, if desired, toppers. Bake 5 minutes more or until crust is crisp, cheese is melted, and vegetables are heated through.
