Traditionally, of course, bubble and squeak is made with left over mashed potatoes and cabbage, maybe seasoned with onion, and fried. But I didn't have any left-over vegetables - well, I do, actually, but neither potatoes nor cabbage - and I wanted this particularly to eat with Nurnberg sausages, which I thought it would complement nicely. It did.
2 medium onions, peeled and chopped
3 medium potatoes, cut into small pieces
1/2 green cabbage (or less - the amount you would prepare for two of you, basically)
1 tbs cooking oil
1/2 tsp caraway seeds
Salt and pepper
Put everything into a large frying-pan and stir. Cover, and reduce the heat. Allow to cook for about 25 minutes, stirring occasionally. Serve with sausages or bacon and eggs or something delicious like that.....
