Pickled onions (양파장아찌)

Another delicious side.  This one goes great with grilled meats in the lettuce wraps.  I've also heard you can drink the juice as you eat the onions up.

Ingredients:
8 onions, sliced
6 green chilies, sliced
3 red chilies, sliced

Sauce:
2.5 cups soy sauce
3 cups water
1.5 cups each: vinegar, sugar

Steps:

1. Put the sliced onions and chilies in a clean, dry, airtight glass container.
2. Slowly boil sauce ingredients in a pot.  When it starts to boil, remove from heat immediately.  Skim off any scum that has gathered at the top.
3. Pour the still-hot sauce over the onions.  Do not cool.
4. Let cool to room temperature with the lid open, then seal and keep in the fridge.

Notes:

- You can eat the onions immediately, or they'll keep for a while in the fridge.
