If you have a smoker, or a friend with a smoker, you can smoke them. That's how chipotles are made.
After smoking, freeze most. The rest can be chopped into mayo/adobo sauce and kept in the fridge for a very tasty slap-in-the-face. 😀
(I smoked mine over charcoal with "slices" of an old maple log I found on the farm. Yummy!)
