Any good recipes for meatless meatloaf or veggie burgers?

I have been reducing my meat intake (my cholesterol is way down, yay!) and my new thought was to make a meatloaf or burger with half the meat. Kind of combine a veggie recipe and my meatloaf recipe so hopefully the flavor and texture is not very different from regular meatloaf.

I am interested in your favorite vegetarian recipes for this sort of thing, and then I will experiment a little. I looked up some recipes, some used potatoes some rice, some lentils, but it would be great to hear from the collective your favorites.
