In a large bowl or blender, combine the milk, Greek yogurt, protein powder, monk fruit, vanilla extract, xanthan gum, and sea salt.
Whisk or blend until the mixture is completely smooth and no protein clumps remain.
Pour the mixture into a clean Ninja Creami pint container, ensuring you do not exceed the max fill line.
Place the lid on the pint and freeze on a level surface for a full 24 hours to ensure a solid freeze.
Remove the pint from the freezer, take off the lid, and place it into the outer bowl of the Ninja Creami.
Process the mixture using the 'Lite Ice Cream' setting.
If the texture appears crumbly after the first spin, add one tablespoon of milk and select the 'Re-spin' function.
Chop the raw almonds into small pieces.
Create a small hole in the center of the ice cream, add the chopped almonds, and process using the 'Mix-in' setting before serving.
