Generally, vegetarian dishes are divided into vegetarian dishes and semi-vegetarian dishes. Vegetarian dishes include eggs, onions, ginger, garlic, celery and other heavy-flavored vegetables. Semi-vegetarian dishes just refuse meat.
There are three reasons:
First, because eggs can develop into chickens, chickens are meat, so eggs are also meat dishes.
Second, eggs belong to birds' eggs in the menu. Birds are meat dishes, so eggs are meat dishes. They belong to the same category.
Third, the difference between vegetarian food and vegetarian food is to classify plant food as vegetarian food, animal food as vegetarian food, and eggs are of course animal food, so they are vegetarian food. There is also evidence that vegetarian restaurants do not use eggs, so eggs are meat dishes.
