I've been making my Meatloaf like this for many years!!
here's what I do:
2-3 pounds good ground chuck
1 can diced tomatoes (drain most of juice off)
1 large onion chopped tiny
salt and pepper
shape into 2-3 loaf shapes in a baking pan,
put some bacon slices on top.
I put mine into a hot oven (400 degrees)
bake it about 15 minutes
then turn the oven down to 350 for 30-40 more minutes.
So I cook it a total of about 1 hour.
You can add whatever else you like, like garlic,
but I like my meatloaf just plain.
this is good and juicy too.
Hope you enjoy it.
I've never put eggs or bread in mine.
