I would continue to add your peelings, cabbage leaves etc and from time to time I'd open the lid and give it all good stirring to aerate and mix it.
I use a long metal spike I happen to have in the garden, but you can buy a compost aerator online. It will continue to breakdown over the winter. It's not the heat that does it (few garden compost bins are big enough to generate enough heat to do that), but a combination of bacterial/fungal action and the work of the worms and slugs that hopefully have found their way into your compost bin.
