Here is a garden of greens I was able to go and pick from:
First they need to be washed - thoroughly, then sliced up.
Then they go into a big pot and seasoned (salt, pepper, vinegar, ham etc.) and simmer for a few hours.
Here is the finished product! A delicious bowl of greens. Of course my pot made a lot of greens, so I put them into various freezer containers and froze them.
As a side note, greens are so good for you! They are packed with nutrition. They are also sold already cut up, ready to cook for your convenience - if you don't have a garden close by!
