Preheat oven to 400° F.
In a large bowl, mix chicken, red onion, and red pepper.
Roll out pastry sheet and slice into 3-inch squares.
Add a spoonful of the chicken mixture to each square. Roll the pastry up so that the two opposite corners are attached.
Bake at 400° F for 15-18 minutes or until the pastry begins to brown.
Enjoy these bites all on their own or with your favorite chutney!
