Press the tofu for 15 minutes to remove excess moisture, then cut into 1-inch cubes.
In a small bowl, whisk together the tamari, rice vinegar, toasted sesame oil, and red pepper flakes.
Heat the avocado oil in a large skillet or wok over medium-high heat until shimmering.
Add the tofu cubes to the pan in a single layer and sear until golden and crispy on all sides.
Toss in the broccoli florets, sliced bell pepper, and snow peas, stir-frying for 3-4 minutes until tender-crisp.
Stir in the minced ginger and garlic, cooking for 1 minute until the fragrance fills the kitchen.
Add the shelled edamame and pour the tamari sauce over the mixture, tossing constantly for 2 minutes until glazed.
Serve immediately in a shallow bowl, ensuring the tofu stays crisp and the vegetables remain vibrant.
