Smoked up some chipotle-onion burgers

Earlier in the week I made a smoked onion(smoked half onions for 90 minutes) and chipotle BBQ sauce, and strained off the onions and chipotle after simmering the sauce for a bit. Thought why not add the bits into some burgers and smoke them up. Absolutely fantastic and will need to do this again when I make more sauce. Served with roasted green beans and onion rings. The burgers had the BBQ sauce, pickles, tomatoes, and a feta sauce.
