I just eat very simply. I diced the onion, then put it in a bowl and poured vinegar on it. Soak the onion in vinegar until the vinegar and onion are completely blended, soak for a while, and then eat directly. By the way, I chose purple onion, the kind with spicy eyes. If the taste is light, people can choose white onions. The soaked onion is not spicy, and it has that sweet taste, which is very delicious, very delicious. Eating this dish can also soften blood vessels and lower blood pressure, killing two birds with one stone.
