Here's a recipe from Jeri over on the thinner.com website. I've tried it and think the tofu really makes a difference in the consistancy of the meatloaf. A few things I would do different are to mash up the tofu with a fork before adding it, and apparently, Jeri makes meatloaf rather flat, while I tend to make it more "loaf-like". She bakes hers for 45 minutes, mine needed an hour and a half. Good luck with the recipe.
Here's the whole "meatloaf" thread on thinner:

Jeri's Meatloaf
1.5 lbs lean hamburger
1 lb sausage (I use pork sage or hot italian)
1/4 c onion, finely minced
1/2-3/4 c mushrooms, sliced and slivered
4 oz can tomato sauce
1/2 c parmesan cheese
4 oz tofu
2-3 tbsp worcestershire sauce
1 egg
I squish it all together with my fingers in a big mixing bowl until completely mixed - not my favorite thing to do but it mixes lots better than a spoon. (I never did splurge on a stand mixer - and now that I'm LC I never will - but it would work really well here) I shape it into a cylinder in a jelly roll pan, flatten, and bake at 375 for 45 min.
Regarding the tofu, which most people are skeptical about, one of my complaints about the same recipe without tofu is that the resulting meatloaf is somewhat tough and hard. Adding tofu made it softer and moister, more like it was made with breadcrumbs, and the resulting taste & texture is great.
And Steel's sugar free ketchup or bbq sauce are good with this - not quite the same as the real thing, but definitely adequate.
