Jamie's Cheeseburger Pie

Ingredients

• 1  egg yolk 
• 1 pound ground beef lean
• 1 sheet puff pastry frozen See Cook's Note
• 5 slices sharp cheddar 
• 1 tablespoon steak seasoning sauce recommended: Dale's Steak Seasoning Sauce
• 1 tablespoon steak seasoning recommended: Montreal
• 0.5 cup onions sweet

Equipment

• frying pan
• baking sheet
• oven
• whisk
• grill

Directions

1. Preheat the oven to 375 degrees F and preheat the grill.
2. Mix the ground beef, onion, steak seasoning, and seasoning sauce together (using your hands is the most efficient way to do this). Form into 5 small flat patties. Grill the hamburgers to medium-well. (You may also pan-fry the patties.)
3. Remove from the grill and top each burger with a slice of cheese of your choice.
4. Roll the puff pastry sheet to flatten slightly.
5. Cut it into 5 relatively even rectangles.
6. Cover each burger with a piece of puff pastry and wrap it around the bottom, pinching all of the edges to seal.
7. Place on an un-greased baking sheet, pinched side down.
8. Whisk together the egg yolk and 1 teaspoon water to make an egg wash.
9. Brush each wrapped pastry with the egg wash.
10. Bake for about 15 minutes, until the puff pastry is nice and brown.
