I only get the small, and I don't load it. I ask for extra black beans, little bit of rice, sweet pork, cheese, lettuce
and the dressing, and usually don't eat the tortilla.
With the tortilla it is 613 calories for how I order it.
Without the tortilla, it is 453 calories.
I've done the large when I am hungrier, and I just do black beans, pork, lettuce, cheese, and dressing. Only 770 calories.
