Easy, adaptable, cheap, healthy, homemade plant based milk
As simple as it gets - add nuts/seeds/oats, water and salt to the blender or food processor and combine. Usually, it's done in a minute.
Strain through nut milk bag or cheesecloth.
If adding flavors, strain first, remove the pulp and then put it back to the blender/food processor with the flavors and mix.
Keep it in the fridge and enjoy!
