It's the 27th. I just cooked up some hamburgers. Hope I don't get sick, but I really couldn't afford to waste that.
Tie it to a stick with hawks rope. drag it outside, around the yard until it becomes a brown mush. stand on one leg and shout at the top of your lungs. you'll see a black guy holding a fish, trade with him and then take the fish out to a movie. come back home, toke up and sell the fish back to the black guy. repeat if needed
You'll know soon enough. I hope you don't like them bloody. I hate wasting food also, everything is so fucking expensive, but I personally would not have cooked 7 day expired ground beef. If I have to blow a sick day or go to work and pop Imodium like tic-tacs, it's just not worth it to me. When I buy meat, I immediately freeze what I'm not cooking the day of purchase or the next day. Good luck.
