Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Drain the sprouted tofu and press it firmly between paper towels to remove excess moisture, then cut it into 1-inch cubes.
In a shallow bowl, whisk the egg until smooth; in a separate bowl, combine the nutritional yeast, garlic powder, sea salt, and black pepper.
Dip each tofu cube into the egg wash, then dredge it through the nutritional yeast mixture until every side is well-coated.
Place the coated tofu on the prepared baking sheet, drizzle evenly with avocado oil, and bake for 25-30 minutes until the crust is golden and crispy.
While the tofu bakes, place the fresh spinach in a skillet over medium heat with a splash of water and braise until just wilted and tender.
Portion the cooked quinoa into a bowl, top with the braised spinach, and finish with the crispy nutritional yeast crusted tofu.
