When I made this soup I used tomatoes with Jalapenos in them. I also doubled the amount of garlic in it. Both of these gave it a little extra kick.
I have made this several times since it showed up in Cooking Light--it is one of my favorite winter stews! I mince the garlic & also add extra.I always use spinach as the 'greens'. Wonderful comfort food with a crusty loaf of bread on a cold night.
