MJ

I have searched the internets for various reports on MJ's favorite foods and this is what I have come up with:
The general consensus is that his favorite food was "Mexican Food", but other speculations came up as well including M&Ms, KFC, spicy food and sushi.

UPDATE: Michael Jordan just confirmed at the Michael Jackson Memorial that he ate KFC with Michael Jackson on the floor of Neverland Ranch. And they laffed.

FURTHER UPDATE: That wasn't Michael Jordan, it was in fact Magic Johnson.
