I have made this soup several different ways. If you want a little more heat, you can sauté a diced jalapeno pepper (do this in Step 1) and/or add a teaspoon of ground chipotle pepper (add this with the other spices.) If you want a little smokiness without the heat, add a teaspoon of smoked paprika with the other spices. You can also puree part of the soup for a thicker consistency. Lots of options!
