Heat the oil in a Dutch oven and add onions and garlic. Let cook till onions are translucent. Add the sliced mushrooms and let cook for 5 minutes. Then add chopped carrots and potatoes and stir. Rinse the lentils and wash them in water to remove the apple cider vinegar. Add to the pot. Add water, bouillon paste, liquid aminos and salt. Let cook/simmer for 30 minutes or until lentils are soft. Add kale and apple cider vinegar and mix to incorporate into the soup. Turn off the heat and add chopped parsley. Taste and add more salt, if needed.
