Place the chicken breasts in the crockpot.
In a separate bowl, mix together honey, soy sauce, garlic, salt, and pepper.
Pour the mixture over the chicken.
Cover and cook on low for 5-6 hours or on high for 3-4 hours, until the chicken is cooked through and tender.
If you want a thicker sauce, mix cornstarch with a little cold water, stir into the sauce, and cook on high for an additional 30 minutes.
Serve over cooked rice or mixed veggies.
