Directions 1. Cook ground beef with onion in a large skillet, stirring continually, until the ground beef is browned and crumbly. Drain in a colander.
2. Return ground beef mixture to the skillet. Stir in ketchup, sour cream, salt and garlic powder.
3. Preheat oven to 375F. Pat or roll each biscuit into a 4-inch square on a lightly floured surface. Arrange the biscuit squares on ungreased baking sheets.
4. Spoon 1/4 cup of the ground beef mixture in the center of each biscuit square. Fold over the corner of each square to form a triangle. Seal edges with a fork. Cut three 1/2-inch slits in the top of each turnover.
5. Bake turnovers until golden brown, 15-20 minutes. Brush with melted butter, if desired.
