I found this recipe in a Campbell's Soup advertisement in a magazine. My whole family loves it! My 5 year old son even loves to help me make it! I usually serve these with spanish rice (out of a box!) and a salad or tortilla chips with the leftover picante sauce.
If you want to make a healthier version of it, use whole wheat tortillas, 98% fat free soup, light or fat free sour cream, and 2% or fat free cheese. I have made it both ways and it tastes great either way!
Also, my prep time doesn't include cooking the chicken since you may have a different cooking method or choose to use precooked chicken.
