Heat milk in a microwave safe bowl (I used my glass measuring cup) for 2 minutes.
Add the tea bag to the milk and steep for 4 minutes.
Once the tea is done steeping, remove the tea bag and whisk in the honey and vanilla.
Dump the rolled oats into a container with an airtight lid and stir in the milk mixture. Put the lid on and place in the fridge overnight.
Wash the blueberries and top your overnight oats.
Grab a spoon and enjoy cold or heat it up in the microwave before adding the blueberries for a quick, warm breakfast.
