Press the tofu for 15 minutes to remove excess moisture, then cut into 1-inch cubes.
In a small bowl, whisk together the tamari, toasted sesame oil, grated ginger, minced garlic, maple syrup, and red pepper flakes to create the glaze.
Heat avocado oil in a large skillet or wok over medium-high heat until shimmering.
Add the tofu cubes to the skillet, seasoning with sea salt and black pepper, and sear until golden brown and crispy on all sides.
Remove the tofu from the pan and set aside on a plate.
In the same pan, add the broccoli, snap peas, and red bell pepper, sautéing for 4-5 minutes until the vegetables are tender-crisp and bright.
Return the crispy tofu to the pan and pour the prepared sesame-ginger glaze over the mixture.
Toss everything together for 1-2 minutes until the sauce thickens slightly and coats the ingredients evenly.
Garnish with toasted sesame seeds and serve immediately.
