Heat the oil in a soup pot, sauté the garlic and onions for 1 to 3 minutes. Add the celery and sweet corn and sauté another 2 minutes. Add the beans, water and sea salt. Cover and bring to a boil. Reduce the flame to medium and simmer for 15 to 20 minutes. Using a potato masher, slightly mash the beans in the pot to produce a creamier texture. Turn off the flame and stir in the pepper and parsley. Serve hot.
