Press the tofu for 20 minutes using a tofu press or heavy weights to remove excess moisture, then cut into 1-inch cubes.
In a small mixing bowl, whisk together the tamari, grated fresh ginger, minced garlic, rice vinegar, maple syrup, and red pepper flakes to create the glaze.
Heat the sesame oil in a large non-stick skillet or wok over medium-high heat until shimmering.
Add the tofu cubes to the skillet in a single layer and sear for 3 to 4 minutes per side until they are golden brown and develop a crispy exterior.
Remove the seared tofu from the pan and set it aside on a plate.
In the same skillet, add the fresh green beans and shelled edamame, sautéing for 5 to 6 minutes until the green beans are tender-crisp and show dark blister marks.
Return the tofu to the skillet with the vegetables and pour the ginger-tamari glaze over everything.
Toss the mixture constantly for 1 to 2 minutes until the sauce reduces into a thick glaze that coats every piece of tofu and vegetable.
Season the dish with sea salt and black pepper to finish before serving hot.
