Place the old fashioned rolled oats in a jar or bowl. Then add the sugar, salt, and cinnamon. Mix them together with a spoon or fork.
Pour in your choice of liquid, milk, water, almond milk, etc. are all good choices. Give the oats a stir.
Add any fruit and nuts that you would like. 1/2 cup is a decent amount of fruit, you could use all of one kind of a variety. I like to use all of one and then top it off when another kind when I am ready to eat it.
Secure the lid on top of the jar or add a plastic wrap to the bowl and place it in the fridge overnight.
The next morning it will be ready to eat. Top it off with whatever else you like and enjoy! It is really that simple.
