I got this recipe off of e-mealz.com. It was not spicy, which is good in our home with small kids. I’m sure you can alter the recipe in a number of ways to make it spicier. I served it with cheese quesadillas to dip in the soup.
In oil, saute until tender 1 cup of each:
Add a couple cloves minced garlic, a tiny bit of salt, and a bit of pepper.
Pour in 4 cans chicken broth (I used one box of chicken broth, which is really only 4 cups) and bring to a boil.
Add a can of diced tomatoes, a can of diced tomatoes with green chilies, a packet of taco seasoning, and 1.5 lbs cooked and diced chicken breast.
Cut 8-10 corn tortillas into pieces and stir into soup. Let boil for 20 minutes until tortillas are incorporated into soup. Stir occasionally.
Lower heat and add 8 oz shredded cheese (I used two big handfuls of shredded cheddar) and simmer for 10 minutes.
Add 1 cup milk and simmer for another 10 minutes.
