It is not appropriate to call it Salad, but I don’t know what else I have to call it, In the Nepali Language we call it Sadeko Bhatmas which means marinated Soybean. But the process of marination is also completely different. Please watch the video for a detailed preparation process. It is traditionally served with roasted or fried flattened rice ( also called beaten rice)

Then, mix in the roasted dry soybeans or green soybeans well with all the  ingredients and spices. This dish can be served as a snack. you can follow the same process with green soybean too.
