Gather ingredients.

Slice onion in half

Slice about an inch of onion horizontally. (This is too thin)

This is better..:)

Heat up your pan with cooking oil.

Put the onion slice on the pan

Put in the egg at the center of the onion. (yeah i know,"duh!") XD

Cook a sunny-side up like you normally would.

You now have an edible egg ring/mold! Tip: you could also use bell pepper and other veggies..;) thanks for looking!
