Easiest way is to add sugar immediately after adding the onions to the skillet and stir fry it. the sugar will dissolve in the juices the onions will release and form an even glaze around every onion piece in the process.
So no need for any olive oil, etc? Just throw some sliced onions in a pan on lower heat and some sugar and stir for a while?
