I think this recipe originally came from a Woman's Weekly recipe book, but it's one I've used almost every week since discovering it. Very simple to make, and the ingredients may not sound exciting, but it is so much more than the sum of its parts. It's a bit like potato dauphinoise but contains no cream and is a complete meal in itself, though it does taste great served with some green veg too, e.g. fine beans. Also it's incredibly easy to use up whatever veg you have lying around. No amounts and measurements given here, just use the amount that looks like it will feed your household, plus a bit extra for seconds!
