Heat oven to 400°F. Lightly grease 12-inch pizza pan or 13x9-inch pan. Unroll dough; place in greased pan. Starting at center, press out with hands. Bake 6 to 8 minutes or just until crust begins to dry.
Top crust with 1/2 cup of the cheese; sprinkle with Italian seasoning. Arrange peppers evenly over top. Sprinkle with remaining 1 cup cheese.
Bake 15 to 20 minutes longer or until crust is deep golden brown and cheese is melted. Cut into wedges to serve.
