This is a quick one-pot soup, which is very easy to put together.
You can use any rinsed bean of your preference. Don't feel obligated to only use cannelloni beans.
Heat oil in large pot over medium high heat; add the onion, garlic, thyme and red pepper flakes, sauté until the onion softens and the flavors meld together, about 3 minutes.
Add the chicken broth, raise the heat to high and bring to a boil. Stir in the tortellini, and cook for 4 minutes.
Reduce heat to a simmer and add the spinach and cannelloni beans, continue to simmer until the spinach has wilted, and pasta is tender, about 1 minute.
Ladle soup into bowls. Serve with Parmesan cheese on the side. Serves 5.
