Carnivore Hidden Deed

I may be horribly wrong, but 3 Roast of Heroes can't possibly be in the deed requirements. It's a one-time quest reward.

I don't know what the proper answer is, but I think it might be 3 Feast of Rohan. My wife and I haven't done the Carnivore deed yet, so we're going to try and get it done between tonight and tomorrow night.
