Spinach Stuffed Tenderloin with Horseradish Sauce

More Beef Please!  On page 100 of Weber's Real Grilling Cookbook you'll find this fantastic way to do tenderloin.  I used my good buddy and fellow carnivor Daniel as a guinea pig and he loved it! The spinanch, bacon, garlic and dill really works.  There's a bit if fresh dill in the horseradish sauce to compliment it as well.  I prefer to buy one large tenderloin, cut the hole through the lengh and fill the stuffing, rather than so 2 or more seperate steaks, but that will work too.
My butcher often gives me deals and he rang it through as beef bones and the cost was $1.73!
