Since he was sent to exile you may place him in the command zone and then pay {1}{G}{W}{U} to put him back into play using his ability.
{Food Chain} does not combo with a commander such as {Derevi, Empyrial Tactician} to create an infinite loop, at least not only with these two pieces.
As for the origional question it would have i be worded as "Exile a creature you control: when a creature is PUT INTO exile this way add mana equal to...etc."
That put into statement would force a check to see if it made it there. There is no form of check in the food chain ability to confirm the card went anywhere. You performed and action of sending a creature to exile and modified that action by creating a different destination. You still met the cost of the ability by sending it toward exile.
