I think I've made something very similar to this in the past but it turned out well enough that I didn't want to forget what I did. So here it goes...
Saute chopped onions and mushrooms in olive oil. Add chopped kale and stir until it begins to wilt.
Cover with water.
Add chicken and beef bouillon, salt, pepper and parsley.
Bring to a boil. Add some chopped potato and some white beans. Return to boil.
Reduce heat and simmer until potatoes are tender.
Add homemade potato sausage meatballs and heat through.
Serve with snails... ;)
