Try doubling recipes to get ahead on cooking and have a dinner or lunch ready for later. Added bonus: this helps to use up extra ingredients that you may have bought specially for that recipe (a bunch of herbs, for instance). Recipes that freeze well, such as stews and casseroles, are great ones to double. Also consider cooking an extra chicken or more meat than you need. The leftovers are tasty in soups, salads, quesadillas or hash later in the week.
