Cut dough into 6 equal pieces. Roll each piece into 2-inch ball. Lightly flour work surface. Place balls on floured work surface. Gather edges of dough around filling, forming pleats all around and pinching edges together at center to seal.
Press center down gently to flatten into disk.
Heat large nonstick skillet over medium-low heat. Brush skillet with melted butter. Lightly brush tops of dough disks with butter. Working in batches, place disks butter side down in skillet. Cook until golden brown, about 5 minutes.
