Step 1

Soak walnuts in lukewarm water for 20 minutes to soften. Drain and set aside.

Step 2

In a medium nonstick pan over medium heat, add the onions and garlic along with 2-3 tablespoons of water. Cook, stirring often, until the onions are translucent and the garlic is fragrant, about 3-4 minutes. Add 2-3 more tablespoons of water as needed to prevent burning. You can also use oil instead if you would like.

Step 3

Add the walnuts and mushrooms to a food processor and pulse until they have broken down into a “meat crumble”-like texture. Add them to the pan along with the cumin, chili powder, tomato paste, soy sauce, oregano, liquid smoke, and 1/4 cup of water. Mix everything together until well combined. Cook the mixture for 8 minutes, or until it beings to brown and the mushrooms soften. If you would like it more moist, add a few additional tablespoons of water as desired.

Step 4

Remove from heat and season with salt and pepper as desired. Mix through the cilantro plus lime juice to taste.

Step 5

Assemble your tacos as desired and enjoy!
