BBQ Pineapple and Caramelized Onion Flatbread (+chicken)

This was fantastic, but of course I had to buy a couple onions of my own and caramelize them the night before because they gave me an onion the size of a golf ball that they wanted me to pickle half and caramelize half.

If you know anything about caramelizing onions for real, it takes at least 45 minutes and it shrinks the onion down to a small fraction of what you start with. Luckily, I was able to caramelize enough to freeze some portions for future recipes that call for it.
