1. Preheat oven to 450°.
2. While oven preheats, shape pizza dough into a 15 1/2 x 10 1/2inch rectangle on a work surface; transfer to a large baking sheet coated with cooking spray. Place in oven on bottom rack while oven continues to preheat, and bake 10 minutes.
3. While crust prebakes, cook sausage in a skillet over medium-high heat until browned, stirring to crumble.
4. Remove crust from oven; rub with sun-dried tomato oil, and sprinkle with sun-dried tomatoes. Top with cheese, sausage, and grape tomato halves. Bake at 450° on bottom rack for 8 minutes or until crust is golden and cheese melts. Cut pizza into 6 rectangles, and sprinkle with crushed red pepper before serving, if desired.
