Carrot and celery bean salad

Soak the beans for 6 hours, then fill it with new water and cook until cooked over low heat for about an hour. Then we throw it into a colander and let it cool down. At the same time, boil the carrots. After it has boiled and cooled, we clean it and cut it into small cubes. The celery root is washed in water, cleaned and cut into thin strips. Lettuce leaves are thoroughly washed and dried with a paper towel, and then we tear them into pieces with our hands. Mix all the components of the salad, pour the sauce and mix again. The sauce is made from mustard, sea salt, granulated sugar, vegetable oil and lemon juice. Salad of beans, carrots and celery spread on a large dish with a slide, bon appetit!
