Unroll pizza dough and place in a greased 15-in. x 10-in. x 1-in. baking pan; flatten dough and build up edges slightly. Prick dough several times with a fork.
Bake at 425° for 10-11 minutes or until lightly browned. Cool on a wire rack.
Meanwhile, in a bowl, combine the sour cream, mayonnaise, cilantro, jalapeno, sugar, chili powder, salt and cumin.
Spread over cooled crust. Toss avocado with lime juice; arrange over sour cream mixture.
Sprinkle with tomatoes, onions, olives and cheese. Refrigerate until serving.
