Sprinkle flour lightly on work surface. Place dough on floured surface. Knead 5 to 10 minutes, sprinkling surface with more flour only if dough starts to stick, until dough is smooth and springy, but still soft. Spray large bowl with cooking spray. Place dough in bowl, turning dough to grease all sides. Cover bowl loosely with plastic wrap; let rise in warm place about 1 hour or until doubled in size.
