The chicken breasts were cut into halves lengthwise (I used 3 filleted into 6 breasts instead of the 6 it called for), then dredged in flour:
I chopped the onion while I browned the chicken in 2 tbsp butter.
Next I added the chicken to the crockpot with the onions, canned jalapenos (I used mild), oregano, and broth that was used to scrape up the brown bits in the skillet:
I'm not sure if my tortillas are too big, but they don't look quite like the picture in the cookbook. But they really were delicious! I'm finding I like slow cooked food! DH liked the enchiladas, even though he kept complaining that enchiladas aren't actually a real thing (whatever that means). I also think that he would have rather had real hot jalapenos, not the mild ones. Funny, the girls ate this one up, but the baby didn't like it. :)
