In a skillet over medium heat, cook the ground beef until browned. Drain any excess fat.
Add the onion powder, garlic powder, salt, and pepper to the beef, stirring to combine. Cook for an additional minute to blend flavors.
Remove from heat and stir in the shredded cheddar cheese, diced pickles, mustard, and ketchup. Let the mixture cool slightly.
Roll out the crescent roll dough on a lightly floured surface. Pinch together the seams to create a sheet. Cut the dough into squares (approximately 4x4 inches).
Place a tablespoon of the beef mixture in the center of each square.
Fold the corners of the dough over the filling to create a pocket, pressing the edges to seal tightly.
Beat the egg in a small bowl and brush the mixture over the tops of the pocket bites for a golden finish.
Place the pocket bites on a baking sheet lined with parchment paper.
Bake in the preheated oven for 12-15 minutes, or until golden brown.
Allow to cool slightly before serving.
Notes
Serve warm with additional ketchup and mustard on the side for dipping. Garnish with fresh parsley for presentation.
