Leftover veg simply loves a ratatouille. If you don’t have everything I’ve suggested, feel free to substitute some of the ingredients for whatever you do have in your vegetable drawer. Use extra courgette if you don’t have aubergine or tinned tomatoes, if you haven’t got fresh. As a bonus, this is the meal that keeps on giving – add a little water to any leftovers and blitz with a hand blender to make a quick pasta sauce.
