Crispy Mongolian Beef - A Favorite! I made this 9/10/16 and it was excellent. I used top round London broil, sliced it thin while it was frozen and then cut it into 1 inch pieces. I omitted the salt (there&#x27;s plenty in the soy sauce), used garlic powder instead of fresh garlic and I added in chopped broccoli (that I had in the freezer) and cooked brown rice at the end. The meat was surprisingly tender and I honestly can&#x27;t wait to make it again. It was that easy and that good!
