Egg in an Onion

1 large sweet onion
1 egg
Salt and pepper

Cut one half off of an unpeeled onion and scoop out most of the interior, being careful not to make a hole the onion. Break an egg into the cavity; sprinkle with salt and pepper. Place the onion directly on the coals and replace the "lid." Cooking time depends on the thickness of the remaining onion walls, but you'll end up with a basically hard-boiled egg and a couple layers of onion.
