3-ingredient Mac n Cheese

My family requests this simple dish every time we eat together - and it's just three simple ingredients - a recipe I copied and learned from my grandmother...

2 bags large elbow noodles
10-12 slices Deli Deluxe American cheese slices
1 stick butter

Boil water and salt it, according to directions, toss in macaroni and cook until tender (not al dente.)

Prepare a 13 X 9 dish with pats of butter on the bottom.

Drain the macaroni well, and place half of them in the dish, layer with half of the cheese, then macaroni again, more pats of butter, and top with the rest of the cheese.

Heat in a 350 degree oven until the cheese melts and runs throughout the mixture...

It's really divine... Don't substitute any other cheese or any other noodle or any other step... :)
