Grilled Ribeye with Gorgonzola Sauce

I don't have a picture of this succulent dish because I sent someone who shall remain nameless to the store to pick up some ribeye steaks and he came back with round eye steaks.  We made do, but I'm going to let you use your imagination to picture how delicious this recipe is. 

This recipe is from the Common Grill Cookbook.
