1/2 pound ground beef
1/4 cup taco sauce
2 teaspoons chili powder
1/4 teaspoon onion powder
1/4 teaspoon garlic powder
1 (10-ounce) package refrigerated pizza dough
1/4 cup shredded cheddar cheese
1 teaspoon water
For filling, cook ground beef in a small skillet until brown. Drain off fat. Stir in taco sauce, chili powder, onion powder and garlic powder. Set aside.
Unroll pizza dough. Roll dough into a 14x10-1/2-inch rectangle. Cut into 12 3-1/2-inch squares. Divide filling among dough squares. Sprinkle with cheese.
Brush edges with water. Lift one corner of each square and stretch dough to the opposite corner, making a triangle. Press edges well with a fork to seal.
Arrange on a greased baking sheet. Prick with fork. Combine egg and the 1 teaspoon water; brush onto turnovers.
Bake in a 425-degree oven for 8 to 10 minutes or until golden. Let stand 5 minutes before serving.
