In a small bowl combine the shredded chicken and barbecue sauce.
1½ cups shredded chicken breast, 1 cup barbecue sauce
Slice hamburger rolls and set aside.
2 hamburger rolls
Transfer the mixture to a saucepan and heat over medium-low heat until the mixture is warmed through but not too hot. Stirring frequently so as not to burn the chicken or sauce.
Once the mixture is warm place heaping piles of BBQ chicken on the bottom bun, dividing the mixture between 2 buns. Add more barbecue sauce if desired. Place the top bun on the sandwich and serve.
