Heat oven to 400°F. Lightly spray 12-inch pizza pan with cooking spray. Unroll pizza crust dough; place in pan. Starting at center, press out dough with hands to edge of pan.
Bake crust about 6 minutes or until crust begins to dry. Meanwhile, in small bowl, mix dressing and Parmesan cheese.
Remove partially baked crust from oven. Spread dressing mixture over crust. Top with chicken, spinach and artichokes. Sprinkle with Asiago cheese. Top with tomatoes.
Bake 15 to 20 minutes longer or until cheese is melted and crust is golden brown. Cut into wedges.
