Making patties from half-cooked ground beef My roommate decided to store a sizable purchase of ground beef in the freezer. For reasons I don't entirely understand, he would thaw it as needed at cook temperature in the microwave, then refreeze.

Quite a bit of this beef remains, and it's been in the refrigerator since I discovered his shenanigans, but unfortunately it's difficult to make patties out of the meat because it's partially cooked. I don't want it to go to waste, so what might I use to hold it together while making burgers that still taste like burgers?
Ground beef is a perfect setting for bacterial growth anyway, Ground beef that has been partially cooked and refrozen multiple times is guaranteed to have a huge amount of bacterial contamination.
