In recent years, grocery store shelves have bloomed with all manner of canned preparations designed to make it easier to throw a meal together fast. Canned gravies and sauces take an idea that started with simple tomato products and condensed soups and add a gourmet touch. You don't have to tinker with a can of cream of mushroom soup to make stroganoff anymore. You can find a canned sauce that will bring more to the table -- literally. Many of these preparations only need the addition of a little meat. If you need to cut precious minutes off your prep time, invest in some of your family's favorite sauces and gravies for a great meal in minutes.
