Our ingredients. Beans are already boiled, salted during cooking.. I don't approve, but if you don't have much time, use canned.
While the beans are cooking, do the rest of the vegetables. Onions with celery fry in vegetable oil. There you can also add black pepper, it opens well in the oil. But, always take into account your taste preferences, you can not add, since carrots are already with pepper.
Onions and celery add to the salad bowl, which are already mixed in the remaining ingredients.
Final analysis. Who love cilantro, and add the salad will be even more beautiful!
