Halve the dates and remove the stones and stems. Chop them into smaller pieces.
Add enough boiling water to cover the dates and let it sit for about 20-30 minutes. Do this previous night if you think you will be short on time when preparing this dish. But mostly while the oatmeal is getting ready, the dates are good to go before serving.
While that`s soaking, bring the milk and 1-1/4 cup water to boil. (you might need more or less depending on the consistency of your oatmeal).
Once boiling, add the oats and salt to the milk.
Mix and reduce the heat to simmer
Cook for about 10-15 minutes (depending on the type of your oats)
Cook until it reaches your desired level of consistency.
Meanwhile, strain the dates retaining some of the soaking liquid. Remove the skin from the dates if you want. You could also opt to do this before beginning the dish - just halve the dates and soak them instead of chopping them further. That way it would be easier to peel.
Now place the peeled dates in a blender along with few tbsp of the soaking liquid.
Blend to a smooth puree.
Add it to your oatmeal or keep it seperately to be added while serving. Add half and keep half while serving.
Add more milk if needed and garnish with the chopped pistachios and additional date puree.
