If you don't have the money or the means to install an in-wall oven or microwave, consider the NuWave infrared oven, a countertop device of “As Seen on TV” fame. Using a combination of conduction (heating the chamber like a traditional oven), convection (moving the heated air around for even cooking) and infrared, the appliance cuts your cooking time by a third. It's perfect for last-minute meal prep, as it allows you to place frozen-solid foods directly in the oven and start cooking right away. AsSeenOnTVpromotions.com
