Huh. In my experience meatloaf really needs some kind of grain component. (can be rice cereal or oatmeal or unsweetened cornflakes or any number of other things rather than bread. I don't remember which end up being low FOADMAP.) This, oddly, actually ends up making it taste moister because the grain absorbs liquid which would otherwise be lost.

Of course, I also tend to think it should involve 2-3 kinds of meat (one of which should be sausage, if reasonable) and a glaze of some kind on top (ketchup, BBQ sauce, tomato sauce, salsa)

I also tend to love my meatloaf pans (Something like this, though I no longer remember what brand I have: http://www.amazon.com/Wilton-Perfect-Results-Piece-Meatloaf/dp/B004VM1DVI/ref=sr_1_3?ie=UTF8&qid=1457352524&sr=8-3&keywords=meatloaf+pans )which let extra fat drip out the bottom.
