My only change was that I added some cooked orzo pasta during the last step. I'm sorry, but minestrone is supposed to have pasta in it. I was surprised that this recipe didn't include pasta. Orzo was just what I had on hand, but you could also use pastas like macaroni, ditalini, and orecchiette.
In a large pot, over medium heat, bring the tomatoes and their liquid to a simmer. Cook for 2 minutes. Add the broth, white beans, and kidney beans (if using) and bring to a simmer. Add the green beans and cook until tender, about 3 minutes. Add the salt, pepper, and spinach and stir until wilted. Ladle into bowls and sprinkle with the Parmesan. Serve with the bread.
Yield: 4 servings
(Note: It actually yielded more like 6-8 servings. You can freeze the leftovers)
