Unroll one 13.8-ounce tube pizza dough on an oiled baking sheet. Brush with sesame oil, then sprinkle with 3 chopped scallions and 2 tablespoons toasted sesame seeds; press into the dough and season with salt and pepper. Drizzle with 2 teaspoons chili oil. Roll up from the short side and cut into 8 rounds. Turn cut-side up and gently press down. Bake at 400 degrees F until golden brown, 15 to 20 minutes.
