Six Sisters' Slow Cooker Honey Sesame Chicken

I found this on the Six Sisters' blog and had to try it. I can never get the sauce to thicken in the crock pot so I put the juices in a separate pan, add the cornstarch and cook it on the stove but I posted as it was written.

Ingredients

• 4  boneless skinless chicken breasts (thighs would be fine too)

3. Cook on low for 3-4 hours or on high 1 1/2 – 2 1/2 hours, or just until chicken is cooked through.
4. Remove chicken from crock pot, leave sauce.
