My first recipe was a simple cabbage soup made with canned tomato soup. That's right: soup was a main ingredient in my first soup. This one is an attempt to capture the essence of that soup, but with better ingredients.The roasted red pepper adds an element not normally found in cabbage soup. The red cabbage darkens the soup and lends a striking purple color. Warning: the chipotle makes this a spicy soup, so remove the seeds if you want it less spicy. Don't omit the pepper, since the smokiness plays well with the other ingredients.
