Well, I am not good at exact measurements, but I make it all the time for DH, and it goes something like this:
1 1/2 pounds mince beef (or something similar, a large pack)
1 medium onion, very finely chopped
1 green bell pepper, very finely chopped
a dash of thyme
about a cup of fine breadcrumbs
about 2 medium eggs beaten
about a cup of ketchup
salt and pepper, however much you like
mix the chopped onion and pepper with the mince, add seasonings. mix the breadcrumbs into the egg separately (this is to avoid getting dry breadcrumbs in the meatloaf) and add this gloopy mixture into the meat mixture with the ketchup. Don't overmix it. transfer to a loaf pan, no need to grease the pan. bake for about 30-45 minutes, then take it out and smear some more ketchup over the top and put it back in for another 30-45 mins. I think I usually have the oven on about 190C, not exactly sure, but just make sure it isn't too hot, and that you cook it for about an hour to an hour and a half, the sides should shrink up from the pan a bit and the ketchup on top should be nicely browned.
There are all sorts of fancy recipes, but this is the simplest way it is usually done in Texas. You can leave out the green onions if you prefer, and some people add carrots or other veg, though I'm not a big fan of carrots.
I am currently planning to work on a recipe with brown sauce instead of ketchup, just for a change.
