Spray an egg cooker with cooking spray

Take half an English muffin, add a little cheese (food glue), add the cooked egg, add a little more cheese (food glue, ya know), add the meat, and add another bit of cheese (more food glue) on top, add the other half of the English Muffin.
Wrap in plastic wrap and freeze.
