I found this article about a couple who lived off the food in their pantry because they spent way too much for Christmas and had to pay their credit card bill. They made it through 147 meals. They were surprised they had so much food in their cupboards that they weren't using regularly.
February is a short month. Maybe it would be a good challenge to eat from your pantry for the month of February and see how many meals you could come up with! If nothing else, you could rotate the old food out and replace it with new food from all the money you save.
