Toaster ovens are more versatile than you might think. Don't limit yourself to heating up bagels and leftovers in yours – use it to cook a delicious dinner, or even dessert. This is an especially useful method in the summer, when you'd rather not heat up your whole kitchen. If you've got leftover roast chicken, shred the meat for the ultimate toaster oven meal: nachos. What's easier than opening a bag of chips, sprinkling on some toppings, and popping it in the toaster? You've got time to make fresh guacamole while the cheese is melting.
