Chop 1 onion and 2 slices of bacon. Put this in a large fry pan with a little olive oil heated in the bottom. Saute until they are started well, stirring occasionally. Meanwhile roughly chop 1 small-medium head cabbage (with stem cut out) then add to the fry pan. Stir together with 2 T sugar and 2 T vinegar, then cover and cook on med/low to low for 40-45 minutes, or until nice and tender. Serves 4-6 people nicely, and oh-so-yummy on a winter's night.
