Add the hot water, textured vegetable protein, and tamari to a mixing bowl. Stir until well combined and let it rest for at least 15 minutes.
Transfer to a food processor and add all the remaining ingredients. Blend until well combined. If the dough is too sticky, add more flour. If you don’t have a food processor, you can mix all the ingredients in a large mixing bowl, but the texture will be better if you use a food processor.
Separate the dough into 28 vegan chicken nugget pieces.
Take one piece, dip it into the flour, shake off all the excess, and dip into the buttermilk (shake off the excess as well). Finally, dip it into the crumb mixture and roll around until fully coated. Repeat with all the remaining pieces.
Heat the oil in a large pot.
Fry the vegan chicken nuggets in the oil until golden brown and crisp. Remove with a slotted spoon, then drain the pieces on a wire or paper towel. Let them cool for at least 5 minutes before serving.
Serve your vegan chicken nuggets immediately with ketchup, bbq sauce, or your favorite sauce.
Keep the leftovers in an airtight container in the fridge for up to 1 week or in the freezer for up to 3 months.
