Vegetable Lo Mein is such a versatile dish. You can add just those veggies that you really like. I wouldn't suggest leaving out the water chestnuts though because they add a great texture to the dish. There is a big difference between Lo Mein and Chow Mein. Chow Mein noodles are fried, such as the ones you buy in a can. Lo Mein noodles are cooked.
