Based on this recipe: http://www.chowhound.com/recipes/chicken-tortilla-soup-30472
Updates:
- Doubled most of the recipe except chicken stock, only used 1 quart stock + 3c water
- Used 8 tortillas
- Added chayote squash
- Used fresh instead of canned tomatoes
- Omitted cayenne and halved chili powder
- Addition of heavy cream didn't seem necessary, maybe omit next time
- Didn't make tortilla strips but just crumbled tortilla chips
- Avocado garnish completely necessary!
