Combine the meat, onion, and beans together.
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 soy sauce to taste, finely chopped garlic to the salad.
And the third secret, if you do not want the taste of garlic to be strongly felt, then you need to put garlic in hot fried meat or in hot fried onions to “extinguish” the taste of garlic.
