Mix hamburger, diced onion,steak seasoning, steak sauce together until well blended.
Make into 5 patties
Grill or fry in frying pan using a little olive oil until burgers are medium well done.
On a flat surface place a little flour out and place the puff pastry sheet on top and slightly roll to flatten lightly.
Cut into 5 rectangles evenly, if possible.
Again roll each rectangle out to fix one burger on.
Place burgers on each rectangle and add a slice of cheese.
Cover burgers by bringing ends together to cover the burger completely.
Place on a lightly greased baking sheet.
Whisk together egg yolk and water.
Brush over the covered burgers.
