Olive vegetable is a kind of pickle made of olive fruit and mustard, which is delicious and nutritious. Although seafood ingredients such as shrimp and salted fish are used in the production of olive vegetables, these ingredients are only used as condiments and are not the main components of olive vegetables. Therefore, from the perspective of food classification, olive vegetables do not belong to seafood. In addition, olive vegetables have high nutritional value and are rich in vitamins, minerals and dietary fiber, which is beneficial to promoting gastrointestinal peristalsis and digestion and can be eaten as appetizers or side dishes.
