Preheat the oven to 375 degrees Fahrenheit.
Remove the tofu from the container and drain out all excess liquid.
Place it between two towels and gently pat it to get some liquid out. If you have time, press it for about 20 minutes, but don't worry if you skip that step, it still turns out great.
Cut the tofu into about 1 inch cubes and add to a food processor.
Add in all remaining ingredients.
Pulse a few times, scrape down the sides, and pulse again. It should only really take a few spins of the food processor to get the right consistency. You want the tofu, walnuts and chipotle peppers broken up, but not completely mushy. See photos for reference.
Transfer to a baking sheet lined with parchment paper or foil.
Bake for 30 minutes, stirring halfway through to break up any larger chunks and to ensure the edges don't burn. When you stir, try to mix it up really well so everything cooks evenly.
Remove from oven and serve in tacos or burrito bowls!
