This is probably obvious to most but i just figured it out so if it helps anyone then great. I used to just throw the frozen burgs right on the grill and cook the and they always suck for the most part, well compared to a fresh one so i just started thawing the before cooking and an they are 100 times better than when you cook them frozen, juicy just damn good, if you don't thaw them now you have to do it. Just leave them on counter for a little or micro defrost them.
