Made just as written (using pork) and it was outstanding! Just purchased all of the ingredients to do it again tonight! Excellent!
My family always frequented a local Chinese restaurant when I was a kid, and egg foo young was my favorite! I added finely chopped mushrooms to the vegetable mix and fried in peanut oil. I also added one can of prepared chicken gravy to the sauce after it was complete because our local restaurant served more of a chinese gravy than a sauce. I passed white pepper at the table. Delicious!
