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, and red pepper flakes.
Heat avocado oil in a large skillet or wok over medium-high heat.
Add the tofu cubes and sear until golden brown on all sides, then remove from the pan.
In the same pan, add the minced ginger and garlic, sautéing for 30 seconds until fragrant.
Add the broccoli, snow peas, and edamame, stir-frying for 3-4 minutes until crisp-tender.
Return the tofu to the pan and pour the tamari mixture over the ingredients.
Toss everything together for 1 minute to coat, then drizzle with toasted sesame oil before serving.
