Step 1

Coat the bottom of a large skillet with oil and place it over medium-high heat.

Step 2

When the oil is hot, add the onion. Sauté the onion for about 5 minutes, until it softens up and just begins to brown.

Step 3

Add the garlic and sauté for another minute, until very fragrant.

Step 4

Crumble the tempeh into the skillet. Cook the tempeh, stirring occasionally, until it begins to brown, about 5 minutes.

Step 5

Stir in the tomato sauce, adobo sauce, cumin, ancho chile powder, salt and pepper. Cook everything for 1-2 minutes more, until the sauce begins to thicken up.

Step 6

Remove the skillet from heat and season the mixture with additional salt to taste. Adjust any other seasonings to your liking.

Step 7

Stuff the tempeh taco filling into shells or tortillas. Top with toppings and serve.
