Is there anyplace here in the general L.A. basin area that makes these sandwiches? I'v been to a lot of places and have never seen them on the menu. These are classic Gudalajara street food. It's basically braised pork--moist not crispy like the american style carnitas--in a really crusty bread roll. To eat it, you soak the bread ina thin non-spicy tomato sauce to soften it and then add as much chile sauce as you can take. The trabajadores in Guadalara skip the tomate and just dip the whole torta in an absolutely viscious salsa.
I asked a friend from Guadalajara and he said the climate's wrong to make the bread. I'm not that sure I can buy that since the climate's just not that different.
