I saw a similar recipe made on TV and tried to duplicate it in order to use up an abundance of Swiss chard that I got from the farm this summer. We have been enjoying it regularly, so I thought I would share it here.
Fry bacon slices over medium heat in a Dutch oven or soup kettle, then remove and drain on paper towels. Saute garlic, onion, carrot, and Swiss chard stems in bacon grease until soft, then add ham, red pepper flakes, and black pepper. Add Swiss chard leaves and saute until they are wilted.
Add chicken broth, Roman beans and tomatoes. Stir together, increase heat and bring to a boil. Lower heat and simmer, uncovered, for about 30 minutes. Add hot sauce and Worcestershire sauce. Crumble bacon slices and add to soup. Stir in Parmesan cheese to taste.
