Homemade Greggs Steak and Cheese Roll

1. Heat the oil in a large skillet over medium heat. Add the sliced onions and cook until they start to soften, about 5 minutes. Sprinkle the sugar and salt over the onions and continue cooking, stirring occasionally, until they caramelize, about 20-25 minutes. Add the minced garlic and cook for another 2 minutes.
2. In the meantime, prepare the beef. Season the thinly sliced beef with salt and pepper.
3. Add the seasoned beef slices to the skillet with the caramelized onions and garlic. Cook for about 5 minutes until the beef is browned on all sides.
4. Pour in the beef stock, add the bay leaves, and stir to combine. Cook on low for 2 ½ to 3 hours, or until the beef is tender.
5. Once the beef is cooked and tender and gravy is thickned, remove it and discard the bay leaves then leave to cool for a hour.
6. Roll out the puff pastry on a lightly floured surface and cut it into squares or rectangles, depending on your preference and the size of the rolls you want.
7. Spoon some of the  beef gravy mixture onto each square of puff pastry, leaving some space around the edges. Sprinkle some chopped Stilton cheese over the beef mixture.
8. Brush the edges of the puff pastry with beaten egg, then fold the pastry over the filling to form a roll. Press the edges together to seal, then place the rolls on the prepared baking tray.
9. Brush the tops of the rolls with more beaten egg for a golden finish.
10. Bake in the preheated oven for 20-25 minutes, or until the pastry is golden brown and crispy.
11. Serve hot and enjoy your homemade steak and cheese rolls!

These rolls are perfect for freezing as well. Simply assemble them, freeze on a baking tray until solid, then transfer to a freezer bag or container. When ready to bake, you can bake them from frozen at a lower temperature of 150°C (300°F) for about 35-40 minutes, or until heated through and golden brown. Enjoy!
