Chicken Drumstick Casserole

I did this in the slow cooker. It was tasty but not spectacular. It smelled great while it cooked. I served it with rice. Served 2 adults, 2 kids.

1kg chicken drumsticks (the large variety)
4 medium potatoes, large dice
2 1/2 large carrots, large dice
1 onion, quartered (you could chop, but my kids don't eat onion so I can still get the flavour but not end up with it in their dinner more easily when I cut it like this)
1.5 cups chicken stock
1 tsp salt
0.5 tsp freshly ground pepper
0.5 tsp thyme (I used dried but I'm sure fresh would be better)
0.5 tsp gravox powder (the gluten free version. It says it contains milk products but that is only dextrose, a sugar, so doesn't contain the milk protein - I think!)

Place in slow cooker and cook on low for ~7hrs or high for ~5hrs. I had to do high but slow is usually better.
Serve with rice and more vegies if you can.
Variations - I think celery would go quite well in this recipe and I was tempted to put a green capsicum in it but it had gone bad...
