I had a pretty good deal with one of my NCO's a little over a decade ago when we were stationed at Charleston AFB; I killed hogs and he cooked 'em up for the both of us. Eventually I PCS'd and he consented to share the recipe. This sauce/marinade will take care of several pounds of meat (I've used beef, wild boar, deer, moose, and all worked just fine) and you can adjust ingredients as your taste demands...
1 cup soy sauce
1/2 cup sesame oil
1 cup sugar
1 bunch sliced green onions
3 cloves of minced garlic (I use more)
1/4 sesame seeds (I prefer roasted)
Crushed red pepper to suit you
Marinate thinly sliced meat for several hours. Grill meat, then dip back in marinade and reheat on the grill or in a pan. Heat marinade in a pot to use as sauce.
Lay meat over rice and cover with sauce. A little kimchee on the side is great and beer certainly doesn't hurt.
