Vietnamese Cabbage Rolls

Everything is well known, for example Japanese cuisine, Italian cuisine. But few people know the recipes for cooking Vietnamese cuisine. And so I decided to somehow fill this gap in my knowledge. I found a recipe, cooked it, ate it with pleasure! So I advise you too!
Soak the rice in cold water for 5 hours, then rinse, dry and mix with a tablespoon of salt. Pre-soak the beans overnight, rinse. Pour boiling water over the beans, let the water drain. As soon as it dries a little, crush it in a bowl, adding a teaspoon of salt. Pass the pork through a meat grinder. Finely chop the onion, mix with pork, soy sauce, remaining salt and pepper. Cut off the thickening from the cabbage leaves, beat off the leaves slightly. Put 1 tablespoon of rice on each, a tablespoon of beans on top, then 1 teaspoon of minced meat. Cover the minced meat with the remaining beans, lay a layer of rice on top. Roll the leaves stuffed with minced meat into tubes and tie with green onions.
Put the cabbage tubes in a wide saucepan, fill with water, cook for 15-20 minutes. Take out the finished rolls, put them under the load for 7-10 minutes so that the excess water runs off.
When serving, put the rolls on a dish, garnish with pickled onions, you can serve soy sauce separately.
This recipe is a bit like Russian cabbage rolls and you can safely replace them on the festive table with cabbage rolls. It will be very unusual and original!
