This recipe doesn't use measurements because you don't need any! For fun flavor combinations, see the list below this recipe.
Take a large bowl or container with a lid, and fill it about halfway with oats.
Add liquid until oats are just barely covered. Add optional salt and some sweetener (better to add less than you need at first).
Stir well. Taste test, and add more sweetener if needed.
Option 1: Cover your bowl and refrigerate it. It will keep for up to 3 days. When ready to serve, set out a variety of add-ins and let everyone spoon out a bowl of oatmeal and flavor it as desired.
Option 2: Stir in whatever add-ins you desire then cover and refrigerate for up to 3 days.
Option 3: Divide the oatmeal into jars and flavor them individually. Cover and refrigerate for up to 3 days.
