Wash the beans thoroughly, place them in a pressure cooker, cover with water, add salt, and cook for about 40 minutes (until tender but still firm to the bite). Soak for at least 2 hours beforehand if desired
Wash the vegetables thoroughly. Peel or trim the carrots, celeriac, and bell peppers and cut them into small cubes. Cut the onions and tomatoes into large cubes
In a pot, briefly heat the cooking oil, add the onion, carrots, bell pepper, celeriac and salt, mix well and sauté for about 2 minutes, then add the Magic Sauce+Carrots and the diced tomatoes and sauté for about 5 minutes
Meanwhile, finely chop the leek and add it to the vegetables in the pot. Add the cooked beans, a little more Magic Sauce if needed, and stir or toss gently so the beans aren't crushed
Cover the pot halfway and simmer over medium heat for about 5 minutes. Then, just before the end, add the finely chopped parsley leaves and stir gently. Season to taste and enjoy hot!
