Soak the beans for 4-6 hours. Boil, adding in the end of cooking a little salt. And here's the first secret: the water from the beans do not drain, leave the beans in water to cool. If you remove the hot beans from the water, the skin of the beans will crack, and the appearance of the beans will no longer be attractive.
Cut the meat into strips and fry.
Cut the onion into half rings and fry.
Connect together meat, onion, beans.
The second secret: add 1/2 Cup of water to the salad, in which the beans were cooked, so that the salad was not dry.
Then add to the salad soy sauce to taste, finely chopped garlic.
And the third secret, if you do not want to strongly felt the taste of garlic, then you need to put garlic in hot roasted meat or hot fried onions to "extinguish" the taste of garlic.
