I've been experimenting with making healthy smoothies for myself and my family. One of the things that's been keeping me busy is preparing tons of fresh vegetables for the freezer. I bought a huge bag of carrots and heard that you could grow the tops in water. So, I tried it! It works! I also tossed an avocado pit in there, just for good measure. Question for anyone who has done vegetable/fruit smoothies (no milk - lactose intolerant!): do you cook your vegetables first to make them easier on your digestive system?
