In a bowl, mix together chicken, cream of chicken, and mixed vegetables. Season with salt/pepper to taste, if desired. Set aside
On a flat surface, roll out crescent dough and carve out 12 squares.
Grease a muffin tin with cooking spray and carefully place 1 square of dough into each tin. Press dough to seam together any holes or gaps.
Add chicken mixture into each tin and bake for about 13-15 minutes, or until desired browness is achieved.
Enjoy!
