Toaster ovens and microwaves are two different kitchen appliances with distinct functions. A toaster oven uses heating elements to cook food and provides a more even and crispy result. It's suitable for baking, toasting, and broiling. On the other hand, a microwave uses electromagnetic waves to heat food quickly. It's ideal for reheating leftovers, defrosting frozen food, and cooking certain types of dishes, such as steamed vegetables.
