Mealtime Magic Cookbook is a neat little paperback size book published in 1964. The author Margaret Mitchell was the head of the Alcoa Wrap Kitchens and Director of Home Economics for Wear-Ever Aluminum. The book contains recipes many different cooking categories; salads, sandwiches, meats, baking, outdoor cooking and even a chapter featuring an Indonesian Dinner Party. As to be expected most of the recipes feature the use of aluminum foil. There are quite a few foil packet meals. It notes that these sandwiches can be prepared ahead of time.
