Scrambling a few diced pieces of cactus into a breakfast taco is a great way to introduce your friends to nopalitos. Similar in taste to green beans, nopalitos add just a touch of intrigue to your morning. Loaded with vitamin C, beta-carotene, fiber, magnesium and calcium, eating cactus is good for you. Add a couple of chopped Serrano chiles to this recipe for a revved up morning taco.
