What say thee???? I tend to do this with steak, burgers, and even pork chops and chicken breasts. I'm not good about getting the food out in the morning to thaw!
....but I have now got a thermapen and a much better feel for how long is long enough to make sure the meat is up to a good IT. I almost never ruin frozen meat on the grill these days.
The only issues I have with this method is there's no marinating or preseason if. I suppose if you marinated of season then freeze that would solve that. Course you have to plan to do that before you freeze!
