1. Preheat oven to 375°F.
2. Pulse all walnut taco meat ingredients in a food processor until the mixture is evenly ground. The consistency should be like rice, but slightly pasty.
3. Spread the mixture on a greased baking sheet and bake for 30 minutes, stirring halfway through to prevent over-browning.
4. Assemble the bowls with your favorite taco fixings.
