Esther's Chicken

This is a recipe we got from a friend years ago and it's still one of our favorite crock pot meals.

1/4 cup low-sodium soy sauce

2 tablespoons brown sugar
2 tablespoons dry sherry
2 tablespoons rice vinegar
2 garlic cloves, crushed with a garlic press or minced
1 teaspoon finely grated fresh ginger
1/4 teaspoon red pepper flakes
2 pounds skinless chicken thighs

Put all in crock pot on high for a couple of hours, until the chicken is cooked through. Serve with rice.
