My favorite butcher shop will run specials on ground beef and bone/skin-less chicken breast in 10# bulk.
I buy 20# of ground beef and fry it all up in two hours. In batches, it has time to drain more fat off. The 10# of chicken breasts will fit in my crock pot. I spice it up and slow cook it. I package the meat up in 2 cup containers and freeze it. It saves meal prep time and dirty dishes.
