I believe I've mentioned before that I like things easy and here's another easy crock pot recipe I found at Crockin' Girls.com. I tweaked it a bit of course, but it was still so simple, my oldest son fixed it while I was working.
Here's your list of ingredients:
4 frozen boneless skinless chicken breasts
1 pckg taco seasoning mix (I used my homemade mix)
1 can cream of mushroom soup
1 cup Picante sauce
1/2 cup sour cream
1 can corn (do not drain)
Put the chicken in the slow cooker. Mix the taco seasoning, soup, corn, and picante sauce in a bowl then pour over the chicken. Cook on low for 8 hours. Mix in the sour cream just before serving. Serve over rice.
