Best Way to Make Burgers From Frozen Patties

I was recently asked by a friend if I had a good way to season a frozen hamburger patty. So how do you season a frozen hamburger patty before they go on the grill, for more flavorful burgers? I will be honest, I have never come across this as we always use fresh patties. Now, we also have the luxury of planning (most of the time) so when I was presented with this question, I didn’t have an immediate answer. The first thing I did was go to the grocery store, picked up a few different boxes of frozen patties, and started cooking.
