First you have to set the oven to somewhere between 250 to 450 degrees
then you take a split english muffen, or if you don't have one take a couple pieces of white bread, or pretty much any kind of bread that you have around
Spread spaghetti or pizza sauce over the tops of your bread products. If you don't have any, use katsup with oregano mixed in
Cover these things with shredded mozzerella, or any other kind of cheese. If you don't have any real cheese, you can use kraft singles, you just tear them in to smaller pieces
cut peperoni, or bologna, or slim Jims, or beef Jerky for all that it matters in to squares of about a centemeter
Hell, if you bought a hamburger at mcdonalds a few hours ago and it is just sitting in the fridge, it will be pretty gross by now. Why not slice up the patty and throw that on?

Put this stuff on a cookie sheet. Put the cookie sheet in to the oven.

Look in every 5 minutes are so. You will be able to tell that it is ready because it will be melty.

You will be suprised at how good it tastes, or, rather, how bad it doesn't taste.

Anyway, that's what I am eating for lunch
