Ah, fried apples and onions, you have saved me on many a hungry fall night. I think, technically, this is supposed to be a side dish for some kind of roast meat. but since I rarely roast meat, I am perfectly happy just serving fried apples and onions on their own. This dish is really the perfect way to use up the glut of apples and onions that comes in late fall and winter, especially when so little else is available fresh.
For each person, thinly slice one onion and one cored but not peeled apple, and also chop well about half a slice of bacon. In a very large pan, fry the bacon and onions together, pouring off excess grease if necessary. Once the onion is soft, layer in the apple rings, sprinkling a teaspoonful of sugar here and there throughout (depending really on your own taste and how sweet your apples are). Cover and leave the apples to soften, stirring them as little as necessary. Once the apples are soft, the dish is ready to be eaten. I serve this with potatoes, but it can go with whatever you fancy.
