d the Mission burrito,which has beans,meat,rice etc. in it.Started apparently in the mission district of San Francisco,and you find this kind of burrito at Chipolte and Taco Bell and other places.To me it is not authenic.Only burritos I have ever had around San Antonio or we made at home was bean and cheese,or bean and meat.Think the mission burrito was a way to use up leftovers.But people love it.
