Living in Arizona I have had opportunity to eat fajitas often at gatherings, restaurants, and have had many family recipes. I was amazed with this recipe and how it surpassed any other fajitas I have ever had. This is a very authentic recipe that you definitely must take the time and make the effort to make. You will be ruined for any other. Its so good as you prepare it you can hardly wait until its time to eat and neither will your friends and family!
