Clean the green beans, boil in salted water for approx. 5 minutes (cook according to instructions for TK). Dice the bacon and fry in the butter-oil mixture until crispy. Put the beans, bacon and savory together in a saucepan, season with pepper and let it steep for 10-20 minutes over a low heat, stirring occasionally. If it is too strong (salty) for you, simply use less bacon.
