One-pan cooking is very advantageous whether over an open fire or woodstove in a Dutch oven or a heavy cast-iron Kettle or frying pan with a good lid. You can cook it and keep it warming over some hot coals. This is not only a way to preserve it between meals (without refrigeration) but have something hot for your work or security teams when they come in out of the cold. Although you could certainly cook these meals in a modern oven on your own home kitchen range, they are idea for those off-grid or under TEOTWAWKI conditions. Our pioneer ancestors had many arts that we should be learning and this is one.
