I found this link that lists the benefits of vegies, since I knew that they had some protein in them. This lists the ones that have higher amounts of protein, which in theory would be better choices than others when trying to get a higher protein percentage when designing your meal plans. I hope this helps, I know I love fresh vegies from the garden with a little butter and some pepper. I love green beans and broccoli, or trees as my 4 year old son calls them. What are your favorites that you enjoy eating as a side?
