Potato chips, United States

 

Potato chips were invented in New York when a chef tried to play a trick on a fussy diner. Now they're one of the world's most child-friendly foods. But think of them this way -- if a single chip cost, say, US$5, it'd be a far greater (and more popular) delicacy than caviar, a prize worth fighting wars over.

 Seafood paella, Spain

 

The sea is lapping just by your feet, a warm breeze whips the tablecloth around your legs and a steamy pan of paella sits in front of you. Shrimp, lobster, mussels and cuttlefish combine with white rice and various herbs, oil and salt in this Valencian dish to send you immediately into holiday mode.

Though if you have it in Spain, you're probably there already.
