Examples of Far-Out Foreigner's Favorite Food include:

Anime and Manga

Ryuk from Death Note loved apples. He knew apples in his own world, but claimed the Earth ones had far superior taste.
- And Sidoh from Death Note develops a love of chocolate from Mello.

Mickey Mouse comics have Eega Beeva, aka. Pittisborum Psercy Pystachi Pseter Psersimmon Plummer-Push, who eats moth balls like sweets.
The Martian Manhunter's love of Oreo Expy's called Chocos (sometimes they're really Oreos, but usually it's the Brand X). At times this love is treated like an addiction.

In Meet Joe Black, Death develops an intense love of peanut butter.

In the 1995 Made for TV Movie version of The Invaders the eponymous invaders liked very fatty foods and smoking cigarettes - it was actually good for them.
Aquamarine added salt to everything she ate, but that probably has to do with her being a mermaid and all and used to salt water.
- Which was actually a pain to the actress who played her, Sara Paxton but it wasn't because she was actually pouring salt onto her food. She was pouring sugar. Lots and lots of sugar.
In Elf, Buddy, a human raised by Christmas elves, grew up on a diet of sugary sweets, so when he goes to the human world, he starts putting maple syrup on everything.

ELF (a clear parody of ALF) from Nicky510 likes to eat soap. He initially mistook it for food, but even finding out that it was not, failed to stop him from eating it at every opportunity.
