Taco Pie is a really great weeknight dinner because of how convenient it is. From start to finish, it's under an hour. But, if you want to make it even easier, you can assemble it ahead of time, wait until the meat mixture is completely cooled, then cover it with foil and freeze it. Then, when you're ready to eat it, you can put the frozen taco pie in the oven. It will take longer to cook (closer to 40 minutes) since it's cooking from frozen. But, that makes it a good meal to make when you're cooking dinner for a friend in need (who just had a baby, is mourning a relative, etc.).
