Slice- Slice onion in half through the root. Place cut side down and chop off the root and tip of bulb, peel skin off. Work slowly with a sharp knife to create the thinnest slices you can across the middle of the onion.
Jar- to a 2 cup/1 pint jar, add the onion slices, salt, oregano, garlic powder and apple cider vinegar. Do your best to stir it up.
Pickle- place the jar (ensuring not metal parts present!) into a microwave and cook on high power for one minute (see note 2). Stir, then place in the fridge for 30 minutes before enjoying.
