This appetizer is perfect for casual entertaining. Set the ingredients out on the counter and have your guests assemble the pizza.
Preheat oven to 450°F. Place pizza crust on large baking sheet.
Toss cheese, oil, chili powder and pepper sauce in medium bowl. Spread 1/2 of the cheese mixture evenly over crust. Top with vegetables, olives and remaining cheese mixture.
Bake 8 to 10 minutes or until cheese is melted. Cut into 2-inch pieces to serve.
