Bad plan: make potato leek soup when you really don't want to eat it at all.

Good plan: put your full batch of potato leek soup into the freezer, and have a peanut butter sandwich and an apple for dinner instead. Then, on some rainy, miserable day a few weeks later, you can get out that frozen soup, heat it up, add some sriracha sauce, ricotta, and cracked pepper, and have nearly instant homemade dinner.

Voila!
