Microwaves save more than time.
Whether you're a gourmet chef or eat on the run like I do, you can trim the fat off your energy bill with a few simple steps when you cook. If you're baking or roasting something for less than a half hour, try a toaster oven. If you cover your oven racks with foil to keep the oven clean, keep in mind that foil cuts the heat flow and increases your cooking time.
