Grill sausage over medium heat 20 minutes or until cooked through, turning occasionally. Grill peppers and onions 6 to 8 minutes or until vegetables are tender-crisp, turning occasionally. Sprinkle sausage and vegetables with 1 teaspoon of the Roasted Garlic & Herb Seasoning while grilling. Cut sausage into thin slices. Cut vegetables into bite-size pieces. Mix tomato sauce and the remaining 1 teaspoon Seasoning.

Stretch or roll dough on a floured baking sheet to a 12- to 14-inch round, about 1/4-inch thick. Brush top of the dough with oil. Place oiled side down on the grill. Close lid. Grill over medium heat 1 to 2 minutes or until grill marks appear on the bottom of the crust. Carefully flip the crust over using tongs or spatula.

Spread seasoned tomato sauce on crust. Layer with 1/2 of the cheese, grilled sausage, vegetables, and remaining cheese. Close lid. Grill 3 to 4 minutes longer or until cheese is melted and crust is browned. (Check pizza often to avoid burning. Rotate pizza, if necessary.) Slide pizza onto the baking sheet. Slice and serve immediately. Sprinkle with additional Roasted Garlic & Herb Seasoning, if desired.
