Our ingredients. The beans are already boiled, salted during cooking.. I don't approve, but if you don't have much time, use canned food.
While the beans are cooking, take care of the rest of the vegetables. Fry the onion with celery in vegetable oil. You can also add black pepper there, it opens well in oil. But, always take into account your taste preferences, you can not add, since carrots are already with pepper.
Add the onion and celery to the salad bowl, which are already mixed with the rest of the ingredients.
Final analysis. Who loves cilantro, add it and the salad will become even more beautiful!
