Q:

Take the phrase "Summer Olympics."  Change 1 letter and rearrange all 14 to name 4 things you might find in a Chinese kitchen.

With an anagram, switching a letter can make it much harder to solve.  Because this puzzle has 4 answers it becomes a process of elimination.  Pull out the obvious ones first and you're left with m - m - s.

A:

Plum - Rice - Soy - MSG
