Step 3: Season the beef.
Stir in the ketchup, mustard, and Worcestershire sauce. Season with salt and pepper, then simmer for 2 to 3 minutes to mix the flavours well. Remove from heat and let cool.
Step 4: Assembling the slippers
Unroll the croissant dough and separate it into 8 triangles. Place the beef stuffing on the widest part of each triangle, then sprinkle with shredded cheddar.
Step 5: Seal and bake.
Fold the dough over the filling and pinch the edges tightly to seal well. Place the turnovers on a baking sheet lined with parchment paper, spacing them out. Bake for 12 to 15 minutes, until golden brown and crispy.
Step 6: Let cool slightly.
Let the turnovers cool for a few minutes before serving. Enjoy your meal!
