Cooking Ideas wanted

I scored a baron of beef at the local WinCo the other day. Almost 7 pounds of meat in one chunk. Picture a round steak that's 2 inches thick! It was $1.48/lb, so I couldn't resist.

Anyway, I'm looking for suggestions on the best way to cook it. I could just chop it into chunks and make pot roast or something. But I'm feeling a *bit* more ambitious.

Suggestions?
