So I made up my own recipe that was loosely inspired by the original. VERY loosely. Here's what I made. It was SO good. Definitely a new family favorite.
1 T. oil 1 c. water
3 oz. ham, chopped 4 c. vegetable broth
1 stalk celery, chopped 2 T. flour
3 carrots, chopped 2 c. milk
1 garlic clove, minced 1 c. swiss chard, chopped
1/2 c. uncooked rice 1 oz. Parmesan cheese
Heat oil in a large pot. Add ham, celery, and carrots. Saute over medium high heat about 8 minutes. Add garlic and rice; saute 2 minutes. Pour in water, scraping up any brown bits from the bottom of the pan. Add broth and bring to a boil. Reduce heat to low. Cover and cook 15 minutes. Combine flour and milk, whisking thoroughly. Add to soup. Cook uncovered for 10 minutes. Add swiss chard and cook for 5 more minutes. Ladle into bowls; top with grated Parmesan cheese.
