Mongolian Beef The serving amount here is a moderate four ounces. For us the husband eats two servings. The recipe makes a generous amount of sauce so you can up to double the meat without adjusting sauce. I use a cast iron pan which I can get screaming hot and stainless steel works too. You will not be able to get a good sear in a nonstick pan as it’s not safe to heat them on high.
