Final answer:
The number of egg rolls in an appetizer and their contents vary by restaurant, commonly including vegetables and meat, with sweet and sour sauce as a customary accompaniment.
Step-by-step explanation:
The question you've asked seems to be about a restaurant menu item, particularly regarding an appetizer that includes egg rolls. Unfortunately, without a specific menu or restaurant in reference, the number of egg rolls included in an appetizer can vary greatly.
Some establishments might serve a pair, while others could offer four or even more as part of their appetizer serving. The fillings inside the egg rolls can differ as well but commonly include cabbage, carrots, and a type of meat such as pork or chicken. As for the sauce, it's often a sweet and sour sauce that is paired with egg rolls. Other dishes you've mentioned, like chow mein with wagon wheel shaped slices of okra and the fried rice, are not typically served with egg rolls but are separate entrees or side dishes you might find at a Chinese restaurant.
The number of egg rolls and the contents within them depend on the restaurant's specific menu. Typically, they come with a sweet and sour sauce as an accompaniment.
