Slow Cooker Chicken with Honey Garlic Sauce

Lately, dinner planning has consisted of asking myself one of these two questions:  What already made food do we have in the freezer? -OR- What can I throw into the slow cooker? In this case, the answer is chicken and some stuff I always keep in the fridge. This is an amalgamation of a couple of different recipes that I'm pretty sure were probably all stolen from the same person.  It is really easy and super delicious.  I usually serve it with rice.  

Slow Cooker Chicken with Honey Garlic Sauce
1.5 lbs chicken thighs (or whatever cut you want really) 
1 cup honey
1/2 cup low-sodium soy sauce 
1/4 cup ketchup  
1 1/2 Tbs. neutral tasting oil (such as peanut or canola)
1/4 cup chopped onion
2 cloves garlic, finely chopped or minced
1/2 tsp salt (or to taste) 
1/2 tsp black pepper
1/4 tsp red pepper flakes (or to taste)  

Combine ingredients in slow cooker.  Cook on low for 4-6 hours, depending on your slow cooker. A 4-quart one is probably the best size.  If you have larger one or one that runs hot like mine, you might even want to check after about 3 hours to avoid drying the meat out.
