Put Hamburger in a bowl and add your eggs , I just use my hands and squish the eggs and meat all together, and some salt and pepper, (eyeball it) Chop your onions and put them in. Add about half the bottle of Ketchup. Then I take a pkg. of Saltine crackers and crumble them in.
I keep adding ketchup and crackers to have it moist , but not falling apart either, enough to keep it's shape on a cookie sheet in a loaf shape. I then douse it all over with ketchup. Cook in oven about 350 degrees for about 35-45 min.
