Cook the minced onion in a skillet with the butter on low heat until they are translucent.
1 tablespoon butter, ⅔ cup sweet onion, diced fine
Add the minced garlic and cook 1-2 minutes more.
2 teaspoons fresh garlic, minced
Turn up the heat to medium and add the diced chicken breast and stir frequently.
½ lb cooked chicken, shredded
Turn up the heat to medium and add the diced chicken breast and stir frequently. Season with salt and pepper to taste.
Himalayan OR Kosher salt, freshly ground black pepper
Remove the skillet from the heat.
Add the herb cheese to the chicken and combine well.
8 oz creamy garlic and herb Swiss cheese
Set aside the chicken mixture while you work with the puff pastry. Start by unrolling the puff pastry on a baking sheet.
2 packages Puff Pastry Dough (I use Wewalka)
Cut off the excess paper and discard.
Using a pastry cutter or knife, cut the puff pastry dough into three equal pieces.
Cut each of the three pieces in half so you have six square pieces of dough.
Add two tablespoons of the chicken mixture to the center of each square.
Use your finger to add a little water to the edge of two sides of the dough.
Fold the dough into a triangle and use a fork to crimp the edges.
Repeat with each of the squares.
Brush each triangle with the egg wash.
1 egg
Bake at 350-degrees F until the pastry is golden brown, about 20 minutes.
