I grabbed a bunch of the random plant items around the kitchen. In total I had 1 peeled cucumber, 1/2 bag of spinach, 1 orange, 2 apples, 1 kiwi, 1 carrot, and celery stalk.
There was a considerable amount of pulp created. This time we just discarded it but I have read you can easily incorporate it into soups or baked goods. This is something I'm down to experiment with.
