Peel and finely dice the onion. Peel and dice tomatoes (or take tomatoes out of the can). Press the garlic cloves. Wash the beans, cut into pieces approx. 3 cm long.
Sauté the onion in the hot olive oil in a saucepan. Add the garlic cloves and sauté briefly. Add the beans and sauté with them. Coriander and cumin with it. Salt. Sauté everything together vigorously until the beans have already lost some of their strong green color. Now add the tomato to the beans. Deglaze with approx. 200-300 ml of water or stock. Bring to the boil and simmer covered or braised for another 20-30 minutes. To taste.
Enjoy lukewarm or cold.
