Hi Pam!
Please see my recipe for "GRINGO TACO SOUP" in this thread to find one with Ranch Salad Dressing in it. It's the only authentic way to make it, along with a pkg of taco seasoning & chopped tomatoes! I should know; after all, I live in the TexMex area right on the Mexican border! If a hotter soup is desired, simply adjust the seasoning to taste, & use jalapeno chiles for part or all of the green chiles.
Eat in good health!!!!
