My husband recently made 
this vegetarian meatloaf recipe posted by Flickr's 
Moonlightbaker.  It was fabulous.  The only modifications he made were using only 1 kind of veggie crumbles (Boca, I think, whatever our grocer had on hand), and omitting the onion.  The green peppers added a really nice flavor/texture, and the glaze on top was outstanding.  The leftovers were really terrific as well.  Even my omni husband enjoyed it!  Definitely a recipe to make again.
