How was the green chile? Did they use chicken instead of pork?
That would be the best clue.
They did not serve "red or green." They only serve red salsa and some ranch type dip which I don't like, but hubby does. I think there is a "green sauce" for certain dishes, but it's not very good.
As for pork, we've never ordered any pork dish at any of the Mexican restaurants in this town. I'll have to check that out. Of course, the restaurant we frequent is full of authentic illegal Mexicans. haha
