Notes

For a thicker soup, feel free to add some corn tortilla chips (crumbled into pieces) to the soup while cooking. All those leftover tortilla chips at the bottom of the bag can be put to good use here.
You can add variety of different vegetables besides the ones suggested. Broccoli, carrots, zucchini, green beans are all good options.
If you do not have adobe sauce easily available, use your favorite taco seasoning and smoked paprika.
