"Food Revolution" chef Jamie Oliver is teaming up with Chipotle for the ultimate Halloween costume contest -- and you can win up to $2,500 -- but you have to dress up as processed food!

Visit Chipotle this Halloween dressed as a processed food product and receive a burrito, bowl, salad, or an order of tacos filled with freshly cooked, naturally raised ingredients for only $2.

To enter the contest, take a picture of yourself in costume at a Chipotle (make sure we can tell that you're at Chipotle in the photo) and submit it to chipotle.com/boorito between October 31 and November 8. After costume experts have taken a look at all of the entries, the winners will be posted on their website November 15.

One Grand Prize winner will receive $2,500, with five runners-up getting $1,000 each. Twenty runners-up will receive a burrito party for 20 guests. Check out the full contest rules here.
