Wow, not sure I can compete with the gruyere soup recipe above - that does sound good! - but here’s my own original recipe, a riff on Portuguese caldo verde. Double down on the sausage if you want.
1 large yellow onion, diced
Several carrots, diced
1 T ground coriander
2 t ground cumin
1 t red pepper flakes or more if you want more tingle
4 cloves garlic, crushed.
4 cups (about) cooked garbanzo beans/chickpeas – best if you start with dry beans that you cook first, because they make a surprisingly tasty and flavorful broth you can then use in the soup. Second best are the quick-cooking kind you can find in some grocery store produce sections. In a pinch, use canned beans – a couple large 29 oz cans, undrained (use the liquid, below)
6-7 cups of either bean cooking liquid or water.
Two large potatoes, diced
1 large bunch kale, cleaned, thick stems removed, leaves chopped.
1 lb of sausage of your choice. Linguica is most authentic, Kielbasa is also good. Firm smoked sausages should be cut into soup-appropriate bite-size pieces. While smoked sausage is the best, I have also used Italian turkey sausage links with the casings removed, and the results were great.
Olive oil
Heat about 3 T olive oil in a large soup pot. Saute onion until it starts to brown. Add coriander, cumin and red pepper flakes, bloom in the oil, stirring. Add carrots, saute them for a few minutes, and then add garlic, stirring constantly so it doesn’t start to brown, cook for one minute. Add potato and kale, stir and cook for another minute. If things are getting a bit dry, add another slurp of olive oil – it’s a key flavoring element, don’t skimp.
Add the beans and the bean broth or water. You’ll want the liquid to generously cover the beans by several inches. Add water if you need to.
Bring this to a lively simmer, and add the sausage. If you’re using uncooked sausages, remove casings, then drop in little pinches into the simmering broth, making little sausage meatballs.
Allow soup to simmer gently for about 30 minutes. Taste, adding salt and seasonings as needed. If you didn’t cook and soak your beans, you may want to add a couple teaspoons of chicken base to the broth if it tastes thin. This will sit nicely in a crockpot, and it freezes pretty well too.
