Press the extra firm tofu between paper towels for 15 minutes to remove excess moisture, then cut into 1-inch cubes.
Place the tofu cubes in a bowl and toss with nutritional yeast until each piece is evenly coated.
Heat the avocado oil in a large non-stick skillet or wok over medium-high heat.
Add the tofu to the pan and sear for 8-10 minutes, turning occasionally, until all sides are golden brown and crispy.
Remove the tofu from the pan and set aside.
In the same pan, add the broccoli, sliced bell peppers, and matchstick carrots with a tablespoon of water; cover for 2 minutes to steam-soften.
Remove the lid and add the minced ginger, minced garlic, and shelled edamame, sautéing for another 2 minutes until fragrant.
Return the crispy tofu to the pan and drizzle with tamari, rice vinegar, toasted sesame oil, and red pepper flakes.
Toss everything together for 1 minute to glaze the vegetables and tofu thoroughly.
Garnish with thinly sliced green onions and serve immediately.
