Peel the potatoes and cook them in lightly salted water as usual.
In the meantime, fry the washed and cleaned beans in 2 tablespoons of oil in a pan until they are cooked through.
Puree the tomatoes to a pulp.
In a separate saucepan, sauté the onions and garlic in 1/2 cup of oil. Add the tomato puree and bring to the boil, simmer for a few minutes. Season to taste with red wine, honey or sugar, salt, pepper and herbs.
Add the potatoes and beans and let everything steep for another 15-20 minutes. Season again to taste before serving.
Tip: It also tastes wonderful with shredded feta cheese and is then only vegetarian.
