Combine the flour, yeast, and sugar in the bowl of a stand mixer fitted with a dough hook.
Add the salt, oil, and warm water. Knead until the dough is smooth and elastic, about 7 minutes.
Transfer the dough to a lightly oiled bowl. Cover and let rise until doubled in size, about 1½ hours.
Divide the dough into 2 pieces. Roll each piece into a thin rectangle.
Spread the dough with pizza sauce and arrange the cheese and toppings down the center. Fold the dough over the filling and cut each piece into 7 pastries.
Arrange the pastries on a parchment-lined baking sheet. Brush with beaten egg and sprinkle with sesame seeds.
Bake at 350°F/180°C until golden brown and cooked through, 25 to 30 minutes.
