Pour the protein shake, almond milk, pudding mix, and almond extract into a small blender and blend until the pudding mix has completely combined with the other ingredients. Pour this mixture into a Ninja Creami pint container.
Freeze on a level surface for 24 hours. Your freezer should be between 9 and -7 degrees Fahrenheit. To avoid getting a bump on the top of the frozen mixture, freeze with the lid off of the container.
Process the Ice Cream
After 24 hours, remove the pint container from the freezer.
Place the pint container into the outer bowl of the Ninja Creami and then process on "LITE ICE CREAM."
If the ice cream is dry or crumbly looking, pour in a tablespoon or two of unsweetened almond milk and then respin. You may have to repeat this process a couple of times.
Pour the chopped pistachios down the center of the ice cream and then process on mix-ins.
Remove the pint from the machine and enjoy!

Notes
Why do you chop the pistachios before adding them as mix-ins?The mix-ins process is not strong enough to break the pistachios up into small pieces. Chopping them up ensures that they are in bite sized pieces and spread evenly throughout the ice cream.
Why does the recipe use almond extract instead of pistachio extract?Almond extract is a lot easier (and less expensive) to find than pistachio extract or emulsion. The almond extract provides the perfect flavor for this recipe.
What if my mix-ins don't mix all the way down the ice cream?When adding the mix-ins, be sure to dig a hole that goes all the way to the bottom of the container. If they are still not mixed all the way in, process on the mix-ins function a second time.
