Press the extra firm tofu for 15 minutes between paper towels with a heavy weight on top to remove excess moisture.
Cut the pressed tofu into 1-inch cubes and thinly slice the red bell pepper.
In a small bowl, whisk together the tamari, rice vinegar, water, and red pepper flakes to create the stir-fry sauce.
Heat the avocado oil in a large non-stick skillet or wok over medium-high heat.
Add the tofu cubes to the skillet and sear for 8-10 minutes, turning occasionally, until golden brown and crispy on all sides.
Remove the tofu from the skillet and set it aside on a plate.
Lower the heat to medium and add the toasted sesame oil to the same skillet.
Add the minced garlic and grated ginger, sautéing for 30 seconds until fragrant.
Toss in the broccoli florets, sliced bell pepper, and shelled edamame.
Sauté the vegetables for 5-6 minutes, adding a splash of water if needed, until they are tender-crisp.
Return the crispy tofu to the skillet and pour the prepared sauce over the mixture.
Toss everything together for 2 minutes until the sauce has thickened slightly and coats every ingredient evenly.
