My sister-in-law made a meatloaf that I really liked:

She sauteed finely chopped onions, carrots, celery and garlic until soft (they were super small). Let that mixture cool. Combine a little parm cheese, rehydrated porcini mushrooms, 1 egg, parsley, Worcestershire and grey poupon. Add the onion mixture and combine well. Combine that mixture with your beef/pork with your hands and form it into a log on a sheet pan. My sister topped it with ketchup, I might use tomato sauce, but that's up to you, just top it with something. Bake for like 30 minutes at 350.
