In a large skillet over medium heat, brown the ground beef until fully cooked and no longer pink, about 7-10 minutes. If desired, add diced onions and sauté until softened, about 3 minutes. Add garlic powder, salt, and pepper, stirring until fragrant.

In a mixing bowl, combine the cooked beef mixture with shredded cheddar cheese and any optional ingredients such as sliced jalapeños. Stir until evenly distributed.

Roll out the store-bought crescent roll or pizza dough on a floured surface. Cut into 4x4 inch squares.

Place a spoonful of filling in the center of each square. Fold the dough over the filling, creating a triangle or rectangle shape. Press and crimp the edges securely.

Preheat the oven to 375°F (190°C) and line a baking sheet with parchment paper. Arrange the pockets on the sheet and bake for 22-25 minutes, until golden brown.

Allow to cool on the baking sheet for about 5 minutes before serving with dipping sauces.
