Ok...I don't usually eat bacon. This is the exception.
(Turkey bacon is fine, and that's usually what I use).
Chop bacon in to small bits and cook in frypan. When it is almost done, add chopped onion. Let it cook for a bit, then add chicken stock, just enough to steam kale, which is already cut up. If the kale has big stalks, cut them small and add them when you add the onion.
Add kale leaf pieces now. Cover with lid. Stir occasionally. It's finished when the kale is soft. May need a little more chicken stock. Steam slowly, don't fry it. Add a few drops of chili sesame oil. Fabulous with freshly ground Indonesian comet tail pepper, ground in mill.
