Preheat the oven to 400°F. Trim the edges of the bread slices and slightly soak them in water, pressing between your palms to squeeze out the excess water.
Place the slices on a flat surface and gently press all over them.
Place the chicken filling (1-2 tbsp) on one side of the slice and roll it tightly, then press the edges to seal it and store it in a paper towel.
Repeat with the remaining bread slices and rest for 5 minutes in a paper towel.
After that, brush the bread roll with butter and bake it for 10-15 minutes in a preheated oven.
Remove the dish from the oven and serve. The rolls are now ready to be served.
Serve with Ketchup or your favourite dip on the side.
Note: Instead of baking, you can fry evenly on a non-stick pan with a minimal amount of oil.
