Purslane: a Tasty Garden Green - This delicious and highly nutritious plant is considered to be a WEED by many and uprooted and thrown away. High in Omega-3 and other nutrients it is a wonderful food and gives the most delicious flavor to a pot of beans. I put it in my pasta sauce as well. It costs almost nothing to grow because I just buy a handful of the live greens at the market and then put the stems in water to root and before long it has hundreds, no, thousands of tiny seeds that sprout very fast and make more plants.
