Simple? Yes! But to do it properly is another story.
Heat up your grilled cheese pan. I am electric and set stove to about 3.5.
Use judgement here.
Get two slices of low nutrition white bread. Get two slices of low nutrition processed cheese. Cut the cheese into strips so that you can lay it all over the bread evenly, lay it way out there so that crusts are covered as well. This is a most important step.
Put other slice of low nutrition white bread on top evenly.
Butter with soft unsalted butter the outside of the breads.
When pan is hot enough, place sandwich into pan and let it brown nicely.
Flip. When second side is browned and cheese is melted take out of pan and serve, sliced on the bias. Serve with tomato ketchup for dunking.
I do a more advanced version and use fresh baked French bread, 2 slices, and use Emmenthaler style, Gruyere, Brie or any good melting cheese.
