Add the chili powder, salt, garlic powder, onion powder, cumin and black pepper in a small bowl, stir to combine well.
Heat the canola oil in a large skillet over medium-high heat. Add the ground turkey to the skillet, sprinkle with the prepared seasoning mix. Stir, to mix well.
Cook the ground turkey until browned, approximately 4-5 minutes, stirring frequently and breaking up the ground turkey with a wooden spoon or spatula.
Add the tomato sauce and 1 tbsp. water, stir well to combine. Lower the heat to medium-low, cover and cook about 15 minutes, stirring occasionally.
Add the black beans and corn to the taco meat and give everything a good stir. Cook, covered just 3-4 more minutes so all the flavors come together.
Take the skillet off the heat, uncover and let the taco filling cool a bit. Once it has cooled, place it in a large bowl and refrigerate while you prepare to make the hand pies.
Preheat Oven to 400°F and Line a large baking sheet with parchment paper.
Remove the pie crusts from the refrigerator 15-20 minutes before using.
Prepare a small bowl with the egg and 1 tbsp. of water, beat well with a fork.
Make the pie rounds, use a large biscuit cutter or, I use an empty 28 oz. can with both ends removed.
Sprinkle a little bit of flour on a large cutting board or a clean surface. Lay out one pie crust dough. Cut out the rounds. Roll it gently to make each round just a little thinner and a little larger. Re-roll the dough scraps, flatten to roughly the same thickness of the original and cut out the remaining rounds.
Working with one round at a time, add a tablespoon of taco filling in the middle. Add a pinch of cheese and a pinch of the sliced green onions.
Using a pastry brush (or your finger) moisten around the edges of the dough with the egg. Fold the dough round in half, press the edges together gently. Crimp the edges using a fork.
Place the taco hand pie on the parchment paper lined baking sheet. Repeat with the remaining ingredients.
Brush the top of the taco hand pies lightly with the egg. Make 2-3 small slits on the top of each hand pie, use a paring knife.
Bake the taco hand pies for approximately 15-25 minutes, until they are golden. Check them after the first 15 minutes, then add 5 minutes at a time until they reach the desired color.
Makes approximately 20 taco hand pies
