hamburger (i'd go 80-20, at least)
vegie beef soup (not with pasta) (do not add water)
green beans or corn or vegie of your choice (actually, you don't need to add any extra vegies if you don't want to)
1 or 2
beef bouillon, cubes, dissolved in a small amount of hot water (like a 1/4 cup)
crushed soda crackers (i use more, but 1 cup is a good start) (i like the texture they add. other people use corn flakes or oatmeal or bread crumbs)
mashed potatoes (these will be used to top the finished meatloaf, so make as much or as little as you want)
Mix everything except the mashed potatoes together and pack into a loaf pan. Bake for about 45 minutes (if not done, cook longer!!!)
Top with the prepared mashed potatoes and return to the oven for about 10 or so minutes. Some people have topped the mashed potatoes with some shredded cheese and then bake for a few minutes.
Remove from oven and serve!
