Regional cuisine.
American Chinese cuisine.
In American Chinese cuisine, it is a stir-fried dish consisting of noodles, meat (chicken being most common but pork, beef or shrimp sometimes being substituted), onions and celery.
It is often served as a specific dish at westernized Chinese restaurants.
There are two main kinds of chow meins available on the market: 1) Steamed chow mein, and 2) Crispy chow mein, also known as Hong Kong style chow mein (see below).
The steamed chow mein has a softer texture, while the latter is crisper and drier.
Crispy chow mein uses fried, flat noodles, while soft chow mein uses long, rounded noodles.
Crispy chow mein has either onions and celery in the finished dish or is served "strained," without any vegetables.
Steamed chow mein can have many different kinds of vegetables in the finished dish; most commonly including onions and celery but also sometimes carrots, cabbage and mung bean sprouts as well.
Crispy chow mein is usually topped with a thick brown sauce, while steamed chow mein is mixed with soy sauce before being served.
There is a regional difference in the US between the East and West Coast use of the term "chow mein."
On the East Coast, "chow mein" is always the crispy or "Hong Kong style."
At some restaurants located in these areas the crispy chow mein noodles are sometimes deep fried and could be as crispy "like the ones in cans" or "fried as crisp as hash browns".
At a few East Coast locations, "chow mein" is also served over rice.
Here, the steamed style using soft noodles is a separate dish called "lo mein".
On the West Coast, "chow mein" is always the steamed style, the crispy style is simply called "Hong Kong style".
There, the term "lo mein" is not widely used.
The crispy version of chow mein can also be served in a hamburger-style bun as a Chow mein sandwich.
There are also variations on how either one of the two main types of chow mein can be prepared as a dish.
When ordering "chow mein" in some restaurants in Chicago, a diner might received "chop suey poured over crunchy fried noodles".

In many of these cases, this particular dish was served over rice and does not included noodles.
In 1946, one of the first companies to market "chow mein" in a can was Chun King.
The product's creator was Jeno Paulucci, the son of Italian immigrants, who developed a recipe based mostly upon Italian spices that would be better catered to the food preferences of European immigrants and some Americans of similar ethnic origins.
To keep cost down, Paulucci ingeniously substituted expensive water chestnuts with lower cost celery stalks that were originally destined for cattle feed.
Paulucci's company became so successful selling canned chow mein and chop suey that President Gerald Ford quipped “What could be more American than a business built on a good Italian recipe for chop suey?"
when praising Paulucci accomplishments with Chun King.
After Paulucci sold Chun King in 1966, the company would be sold several more times more until it was dissolved in 1995.
