1
In a hot skillet, heat oil. Add onions and cook until brown and caramelized. Stir frequently and be careful not to burn. Add garlic and vinegar. Reduce heat to medium low and cook a few more minutes until the liquid is fully absorbed. Remove from heat.
2
Stir in meat and cheese.
3
In the meantime, use a rolling pin to seal the creases of the puff pastry. Use parchment paper on either side to keep from sticking instead of flour. Cut into squares in any size of your choice. I like to do small ones (about 4 inches or so). Curl up the edges slightly to make an edge. They do not need to be perfect however -- this dish looks its prettiest rustic style.
4
Brush the outside edge of the pastry with the egg wash.
5
Fill each pastry square the mixture.
6
Bake in a 375 degree oven for about 8-12 minutes, or until browned on the edges.
7
Enjoy!

Tips for the best results

Read through all the steps once before you start and measure out your ingredients first — it makes everything go more smoothly.
Preheat the oven fully and bake on the middle rack for the most even results.
Check for doneness a few minutes early — a toothpick in the center should come out with just a few moist crumbs.
Let it cool before slicing so it sets properly and holds its shape.
Store leftovers in an airtight container in the fridge and enjoy within a few days.
