Peel and chop the onions and garlic cloves. Fry the onions, garlic and chilli flakes in hot oil in a pot. Steam the bean seeds briefly. Season everything with grated zest of 1 organic lemon, salt and pepper.
Add 200 ml water, bring to the boil, cover and cook for about 10 minutes. Leave to cool. Wash parsley and mint and pluck. Add lemon juice and olive oil to the beans and blend everything finely with a hand blender. Season with salt, pepper and 1 pinch of sugar. Let it cool down. Thin flatbread goes well with it.
