Last night on Bravo’s “Top Chef: Las Vegas,” the remaining 12 contestants were asked to rough it, literally. But first, a unique quickfire challenge that would be judged by special guest Tim Love, who was a contestant on “Top Chef Masters” and owns Lonesome Dove Western Bistro and The Love Shack in Fort Worth, Texas. The challenge, as voted on by TV viewers, was to cook something using a unique ingredient–cactus. Thankfully this beat out the other two possibilities–rattlesnake and kangaroo. (ewwwww).
