One easy way to make healthy snacks at home is to use a dehydrator to transform fresh fruits and veggies into delicious treats. But investing in a dehydrating machine can cost hundreds of dollars -- excessive if you don’t plan on dehydrating every day. Some recommend using your oven as a dehydrator; all you need to do is set the oven to the lowest temperature possible, crack the door open and let it slowly dehydrate your food overnight. But this uses a ton of energy and adds heat to a home -- not to mention the safety hazard. So forget the full-size oven and look toward a toaster oven instead. It’s more energy efficient, and it has vents to release moisture.
