2Soften yeast in warm water. Combine milk, butter, sugar, salt, and egg in mixing bowl. Cool to lukewarm. Add 1 cup flour; beat well. Stir in yeast. Add remainder of flour, stirring to form a stiff dough. Cover; let rise in warm place until light and doubled, about an hour. Roll out dough, half at a time, on floured surface to a 14x8 inch rectangle. Cut into 8 7x2 inch pieces. Cut your cheese into sticks about 6 inches long and 1/2 inch thick. Place one in center of each piece of dough. Sprinkle each with onion powder or 1/2 teaspoon finely chopped onion. Bring edges to center; pinch to seal. Seal ends. Place seam-side down on tray. Cover; let rise in warm place, about 30 minutes. Fry in heavily buttered skillet on medium heat (325-350) about 2 minutes on each side. Turn carefully to brown all sides. Add more butter as necessary. Serve hot.
