That's the only thing besides chili I already use it for! I like to mix my chicken breasts with a jar of salsa and pack of taco seasoning, and some canned, rinsed black beans
I'm that weirdo that can't eat things like that without some rice though (I usually skip the tortillas and make mine "bowl" style)...maybe I'll start making a big batch of rice when it's cool at night and divide it up for use during the week.
I really need to try that crockpot burrito bowl recipe. I'll probably always prefer mine made separately (because cilantro rice, basically) BUT the convenience factor might outweigh that.
