Fantastic Flank Steak Fajitas Recipe


If you have a craving for Tex Mex, try adding these zesty flank steak fajitas to your dinner menu.  Once you marinate the meat and have the vegetables prepped, this fantastic flank steak fajita meal goes together fast.  It is healthy, colorful, and very tasty.  I love making a homemade Guacamole to go along with these fajitas. In summer, fresh garden tomatoes are also an excellent addition.  Traditional fajitas mix in grilled onions and bell peppers, but you can also get creative with your favorite vegetables such as adding zucchini.   Serve with some rice and beans and you are in for a feast!
