For time-savings, use precooked, diced rotisserie chicken in place of raw chicken.
Directions
Heat the oil in 3-quart saucepan over medium-high heat. Add the chicken to the pan; cook and stir 5 to 7 minutes or until no longer pink.
Add the taco seasoning mix, broth, green chilies, and tomatoes and chilies. Cook until thoroughly heated, about 8 minutes. Remove from the heat and cool slightly.
Whisk 1/2 cup of the sour cream into the soup.
For each serving, place 1/2 cup crushed chips in the bottom of a soup bowl. Top with the soup.
Garnish with dollops of the remaining sour cream and additional chips, if desired.
