Taco Filling
  1. Cut onion into a small dice. Mince mushrooms by hand, or in a food processor. Mince walnuts by hand, or in a food processor. (Do separately from mushrooms). 

  2. In a large skillet, heat oil over medium-high heat. Add all but 3 Tablespoons of diced onion and cook, stirring frequently, until starting to brown, about 5 minutes. Add minced mushrooms, tomato paste, spices, and salt, and cook for about 5 minutes. 

  3. Once the liquid has mostly evaporated, add minced walnuts and cook for about 2 minutes.

Recipe Notes

*I like to use a pure chili powder, such as a ground guajillo or ancho chili powder, but a blended chili powder (includes other spices) works too.
