sausage spinach black bean soup

i'm always looking for some kind of new healthy soup recipe that doesn't involve cream or butter. so you can imagine my excitement when i found this great weeknight meal for those cold winter nights via know whey. i altered the recipe a little bit based on what i already had in my pantry. the soup turned out really delicious and i don't think i'd change a thing. the red pepper flakes made things a little spicy so make sure to use at your own discretion.

ingredients:
2 cans black beans, drained and rinsed
8 cups chicken stock
1 large yellow onion, chopped into small pieces
4 cloves garlic, minced
1 lb chicken or turkey sausage, quartered and cubed
1 lb baby fingerling potatoes, halved
1 bag of fresh spinach (6-8oz depending on brand)
1 can diced tomatoes, with juice
3/4 of a small can of tomato paste
1 red bell pepper, seeded and cut into 1 in cubes
2 teaspoons sweet smoked paprika
1 teaspoon herbes de provence
1/4 teaspoon red pepper flakes
s&p
evoo

directions:
heat evoo in a large stock pan over medium heat. add onion and cook for 5 minutes. add the garlic and sausage and cook until browned. add stock and beans. simmer for 10 minutes. next add tomatoes, red bell pepper, tomato paste, paprika, herbes de provence and red pepper flakes. add potatoes and cook 20 minutes more, then add spinach and finish cooking until potatoes are done. add s&p if needed. serve with fresh hot bread for dipping.
