What's this yummy pickled cabbage stuff...

I get at one of the Mexican restaurants here? It has finely shredded cabbage, tomatoes, jalapenos, and I can taste cilantro. They bring a dish of it with the salsa and tortilla chips (hot from the fryer, YUM). There’s another type of shredded cabbage that comes with the entree-sweeter and no peppers. This restaurant is the only one I have ever been served this type of dish in, and I was born and raised in SoCal. Any ideas?

Curtido?
