Kidney beans soup with cabbage

This is a very heavy soup (in Portugal, sopa de feijão encarnado).

What you'll need:

- 2 cans kidney beans
- 1/2 green cabage (couve lombarda ou couve-coração)
- 1 big potato
- 1 onion
- 2-3 carrots
- 2 cloves of garlic
- a bit of vermicelli
- salt

How to do it:

In a big pan put water with salt and add the liquid from the cans of kidney beans. Peel the potato, onion, carrots and garlic cloves, add to the water and boil until tender. Add half of the beans. Blend the whole thing to a liquid cream. Add the shredded cabbage and bring to a boil again. Add the vermicelli and cook until the cabbage is tender. Then add the rest of the beans.
