For example, a roast served for Sunday dinner can be used for lunches in the form of roast beef sandwiches or vegetable beef soup. After planning several weeks of menus, you'll get the hang of it. Also, be sure and save your menus to use again after a few weeks have passed. Prepare several meals at once and in advance. Cooking and freezing meals ahead of time is a wonderful way to save time and money and can be done in several different ways.
Some people use one day a month as cooking day and spend that entire day cooking and freezing meals.
Others use a few hours a month and put away several dishes and still others cook twice as much for each meal and freeze half. I use a little bit of all of these techniques. Finding an entire day in which to cook is usually a bit more time than most people can spare although I have found ways to do it once or twice a year. The only drawback is that it doesn't yield many meals at one time. My favorite method of cooking ahead is to prepare similar meals at one time.
