3 large onions, sliced thinly
3 T fresh thyme
1/4 cup honey
4 large garlic cloves, chopped
1 cup Apple cider vinegar
2 cups stock

Add the sliced onion, thyme, honey, and garlic. Ad salt and pepper and cook, stirring frequently, for about 20 minutes until onions are browned and very soft and caramelized.
Add the vinegar and scrape the pan to deglaze. Add the stock and bring to a bubble.
Put the chicken back in the pan and cover. Reduce heat to medium for 15 minutes, flipping the chicken halfway.
Uncover and bring heat to high and cook 4-5 minutes more until sauce is slightly thickened.
