Wash and clean the beans and cut into pieces approx. 4 cm long. Rinse the savory and shake dry. Save 3 twigs for the pasta, pluck the leaves off and chop the rest. Bring the spaghetti water with 0.5 teaspoons of salt and the 3 sprigs of savory to the boil. Put in the beans and spaghetti and simmer for 7-8 minutes.
