AVOCADO PITS: The pit from an avocado has an unexpected purpose! Instead of trashing it, store the avocado pit in the jar with your guacamole. It will keep it from turning that brownish color and will even help the store-bought kinds keep their color longer.
PEANUT BUTTER JARS: Don’t toss empty jars of peanut butter if there’s still some peanut butter left on the walls of the jar. It makes an excellent container for making overnight oats. Once you add the oats, milk, and other ingredients, it becomes effortless to stir the peanut butter into the overnight oats and give them a great flavor!
