How much time do you spend chopping up fruit, vegetables, and other dinner ingredients? The annoying task of slicing and dicing wastes precious minutes and causes hand cramps to boot. Thankfully, the Chef'n VeggiChop Hand-Powered Food Chopper does the hard work for you. The gadget replaces a knife to cut up any ingredient, which comes in handy when making guacamole, pesto, hummus, and other recipes that require finely diced or puréed foods. To use, simply place your food in the container and pull the cord to activate the sharp chopping blades. Available on Amazon; $20.
