Add your groceries to your Lexi's Kitchen list along with their expiration dates to stay on top of what you have in the fridge and what will expire next. When you open the skill, it will immediately tell you if you have any expired items in your list, and if you don't have expired items, it will tell you the next item that will expire. You can ask Lexi's kitchen to add items, delete items, list all items, or to tell you the next item that will expire on your list.
