Unroll pizza crust onto an ungreased 14-in. pizza pan; flatten dough and build up edges slightly. Prick dough several times with a fork.
Bake at 425° for 7 minutes or until lightly browned. Cool on a wire rack. Spread pizza sauce over the crust; sprinkle with mozzarella cheese.
Place one pepperoni slice in the center of the pizza; chop remaining pepperoni. Sprinkle some chopped pepperoni around the outer edge of pizza, leaving 1/2 in. of crust. Sprinkle remaining pepperoni in a circle between center slice and outer edge. Arrange cheddar cheese and green pepper alternately in a spoke pattern.
Bake at 425° for 12 minutes or until cheese is melted and pizza is heated through. Yield: 1 pizza.
