Well I don't know about you but, for me, when the weather starts chillin' and it's a quiet night at home--it's time to make some comfort food.  As a child growing up in my home, old standby's were dishes like meatloaf, or this one for hamburger casserole.  This was handed down by my step-father, who later came to be known as Grandpa Stan. So here is his recipe for hamburger casserole.
Depending how many your feeding, you may want to double this recipe.

Start by browning 2 pounds of ground beef.  I use the 80/20 blend.  Season with fresh ground black pepper, and leave out the SALT until later. (be sure to rinse meat and drain well before assembling casserole, this will make or destroy this dish.).
Now while the beef is browning, you want to open 2 cans of corn; one whole kernel, the other cream style. Drain the whole kernel corn, mix the two in a bowl, and add 1/2 teaspoon of salt here, mix.  Now this next step is entirely up to you, either way will work.  You need to make instant potatoes to serve 6, or peel boil and mash russet potatoes to equal amounts, roughly 2 1/2-3 lbs of medium to large size, or 5lbs of small to medium sized potatoes.
So when all your ingredients are assemble, you're going to layer in a 9x13 or larger lightly sprayed baking dish, first the hamburger, then the corn, then by spoonfuls add the potatoes to top off casserole.  Now it was always the habit of Grandpa Stan to top his casserole with sliced green pepper rings, with a square pat of margarine/butter inside these rings. (this really adds such a wonderful hint of flavor to the dish. Cover with foil, and bake in a 350 degree oven for twenty minutes, remove foil and turn oven down to 325 for the last 10 minutes.  It's that simple and that delicious!  Enjoy!           P.s. you can dress this up in a variety of ways, like adding cheese between layers, or in the potatoes. Experiment!
