There are numerous unconventional uses for kitchen appliances beyond their intended purposes. For instance, besides making waffles, a waffle iron can be used to prepare various dishes like grilled cheese sandwiches, caprese sandwiches, nut butter and jellies sandwiches, or ham and cheese paninis as mentioned in the context above. Other examples include using a toaster oven to make cookies or reheating leftover pizza on an electric griddle instead of using a microwave. These creative uses not only showcase the versatility of kitchen appliances but also allow for experimentation with different cooking techniques.
