You can also just cook frozen ground beef. If the first step is browning the meat in the pan, just toss the frozen brick in there.

You're still out of luck if you want hamburgers or meatloaf or something.

With chicken, you can just put it in the oven or crock pot still frozen, just allow extra time to cook and temp it first. It's best to cook it in sauce or something if you're gonna do that though since you can't really season frozen chicken.
