George, our old friends said they learned to do the Mongolian BBQ while he was stationed in the Phillipines. He said the original way was that they cooked the ingredients on their shields over an open fire. Of course in Dallas, he had a fair sized charcoal grill, he took the grate off and had a large round flat sheet of steel (1/4" to 3/8" thick perhaps) that he put on in the grate's place, making a pretty large flat griddle. I remember the chicken was cooked, deboned and chopped up, the beef and pork were still raw, sliced in small pieces, there were alfalfa sprouts, a couple of kinds of shredded cabbage, shredded carrot, maybe some bell pepper and onions, then several bowls of liquid (garlic water, soy sauce, ginger water, and I don't remember what all). You filled your bowl, took it to him, he dumped it on the very hot griddle, stirred and turned it with a large metal spatula, and scraped it off into your bowl again. It cooked pretty fast on that hot griddle
