Add the rolled oats into a mixing bowl or jar.
Spoon in the Greek yoghurt and mix until the oats are fully coated.
Pour in the milk if using, then stir to reach your preferred consistency.
Add honey or your chosen natural sweetener and mix well.
Let the mixture rest for 10–15 minutes, or refrigerate overnight for a softer texture.
Before serving, add sliced banana or berries on top.
Sprinkle with almonds, chia seeds, and cinnamon for extra texture and nutrition.
Serve immediately or store in an airtight container if preparing ahead.
