Unroll pizza dough onto a baking sheet coated with cooking spray; pat dough into a 14 x 10-inch rectangle. Bake at 425° for 5 minutes; set aside.
Heat oil in a nonstick skillet over medium-high heat. Add red bell pepper, basil, oregano, and garlic; saute 5 minutes. Remove from heat; stir in artichokes and mushrooms.
Sprinkle half of cheese over prepared pizza crust, leaving a 1/2-inch border. Spread the vegetable mixture evenly over cheese, and top with remaining cheese. Sprinkle with cracked pepper, if desired. Bake at 425° for 10 minutes or until crust is lightly browned.
