Optional garnish: avocadocheese, sour cream, salsa, chopped tomatoes, pickled red onion (delicious and so easy!), sliced scallions
In a large stock pot, heat olive oil over medium heat, and saute carrots and onions 5 minutes. Add garlic and cook 1 more minute.
Add cumin, chili powder, thyme and salt. Stir.
Add broth, tomatoes, chiles, chicken and cabbage and simmer for 30 minutes on low.
Add tortillas and corn and simmer another 10 minutes.
Adjust seasonings to your taste (you'll probably need more salt if you used low sodium chicken broth).
Stir in cilantro and lime before serving.
Garnish with your selection of toppings.
Broth-based soups always taste better the day after, so if you put the basics together the night before, just stir in the lime and cilantro the next day.
We like a little fire in our soup, so I add a few shakes of Tabasco.
