Who would have known such a prickly looking plant with pretty blooms was such a treasure trove? The Prickly Pear cactus (Opuntia ficus-indica) not only looks cool, but it is edible! Apparently there are health benefits to including this crazy plant in your diet. You can eat the flat paddle like leaves known as Nopal and the fruit known as Tuna. There are many recipes for both the Nopal and Tuna parts of the cactus.
