Place yoghurt, oats, milk, chia seeds, honey (if using) and salt in a jug or bowl. Stir to combine.
Set 3 of the strawberries aside (choose the best looking ones!) and roughly chop the remaining quantity. Stir half of these into the oat mixture and refrigerate for at least 3 hours, or overnight, until thickened. Refrigerate the remaining chopped and whole strawberries as well.
When ready to serve, divide half of the oats between 3 glasses or small jars. Add half of the remaining chopped strawberries on top, then repeat with remaining oats and chopped strawberries.
Dollop extra yoghurt on top of parfaits and add a whole strawberry on top.
