These Chipotle Barbacoa Burritos are one of my favorite Mexican dishes. We start out with a beef chuck roast, which is seared on a pan and then slow cooked to perfection. The secret to this beef barbacoa's flavor is in the sauce, which includes smoky chipotle peppers in adobo sauce, cumin and a splash of lime juice.You can also make this into a Chipotle Barbacoa Bowl by omitting the tortilla!
