Preheat oven to 400°. Grease a baking sheet. On a lightly floured surface, roll dough to form a rectangle, about 1/4 inch thick. Transfer to prepared baking sheet. Spread pizza sauce over half of the dough. Sprinkle cheese over entire piece of dough to within half inch of all of the edges. Layer broccoli on one half of the long side of the dough. Fold dough in half over the cheese and broccoli filling. Seal edges of the calzone by pressing with the tines of a fork. Prick top. Brush top with butter. Bake for 20-25 minutes, or until crust is lightly browned. Allow to cool for 5 minutes before cutting.
