MRS: These are the best use of left-over vegetables ever. And those veg could be roast potatoes and carrots, steamed green beans, cauliflower or broccoli or sautéed mushrooms … it doesn’t matter really, just as long as they are already cooked. If you had some meat you could use that as well, like cooked sausages, bacon, meatballs or roast chicken. I quite often make these at breakfast time when we have a surplus of eggs and no bread for sandwiches for lunch. They take no time to prep and are cooked while I am nagging the hooligans to get dressed … again!
