Cook the beef: In a skillet over medium heat, cook the ground beef until browned. Drain any excess fat, then stir in the taco seasoning mix (and water, if required according to the seasoning packet instructions). Set aside to cool slightly.

Prepare the dough: Unroll the pizza dough onto a lightly floured surface. Stretch it into a rectangle and cut it into 5 equal pieces (about the size of the cheese sticks).

Assemble the taco sticks: Place a halved cheese stick in the center of each piece of dough. Spoon a generous amount of the taco meat mixture over the cheese, then fold the dough over the filling, pinching the edges to seal the sticks.

Brush with butter: Place the filled sticks onto a greased baking sheet. Brush each taco stick with melted butter, then sprinkle with garlic powder and dried parsley.

Bake: Bake in a preheated 375°F (190°C) oven for 12-15 minutes, or until the dough is golden brown and cooked through.

Serve: Serve warm with your favorite dipping sauces, like salsa, sour cream, or guacamole.
