Overnight oats with berries

To get ready tomorrow's breakfast, in a glass jar with a lid or a ceramic mug with a lid, combine:

1/2 cups rolled oats (preferably the slow cook kind)
1/3 cup of milk or cold water
1/3 cup whole milk plain yoghurt
1/2 - 3/4 cup of frozen berries ... I use a mix of raspberries and blueberries
optional: 1 teaspoon of maple syrup

Stir well, put on the lid, and place in the fridge overnight.

In the morning, stir again and top with toasted whole hazelnuts or any toasted nut of choice.
