Step 1

Combine tofu, tamari (or soy sauce), chili powder, garlic powder and onion powder in a medium bowl. Heat oil in a large nonstick skillet over medium-high heat. Add the tofu mixture and cook, stirring occasionally, until nicely browned, 8 to 10 minutes.

Step 2

Meanwhile, mash avocado, mayonnaise, lime juice and salt in a small bowl until smooth.

Step 3

Serve the taco "meat" with the avocado crema, salsa (or pico de gallo) and lettuce in tortillas. Serve topped with pickled radishes, if desired.
