Bills and Chiefs fans with a blank space in their tummies are in luck this weekend  ... Buffalo's food service partner just revealed it's going to sell some Taylor Swift-themed snacks at the big game Sunday!!

Delaware North -- which has brought tasty treats to Highmark Stadium all season long -- announced this week it's packing two new options for the divisional round playoff game against Kansas City with odes to Swift in them.

One of the meals is called the "Bad Blood waffle fries" ... and it features two feet of fries topped with a grip of Buffalo and Kansas City food staples -- including blue cheese and BBQ pork.

The other option is named the "Karma Quesadilla" ... and it's got chicken tenders, bacon and pork belly all over it.

It's not quite clear if Swift will get the opportunity to enjoy the grub -- it hasn't been confirmed yet if she'll make the trek to Orchard Park to watch her boyfriend, Travis Kelce. But, considering she battled the snow to catch his game last weekend against the Miami Dolphins, it seems like it's a good bet.
