The Italian appetizer is classic and the production difficulty is zero. It is elegant and sweet with a uniquely made sour and sweet sauce.
Choose a larger dish and arugula.
Slice the tomato on top of the arugula.
Mozzarella cheese is cut into small pieces and continues to be laid. If you buy a ready-made small ball type, you don't need to cut it.
Stir in the black vinegar and mix well. (Children's shoes in foreign countries can directly buy supermarket ready-made sweet balsamic vinegar)
Just stir before eating and you can eat!
