Drain and press the extra firm tofu for 15 minutes to remove excess moisture, then cut into 1-inch cubes.
In a small bowl, whisk together the coconut aminos, rice vinegar, and toasted sesame oil to create the stir-fry sauce.
Heat a large non-stick skillet over medium-high heat and add the tofu cubes, searing until they are golden brown on all sides.
Add the broccoli florets, sliced red bell pepper, and shelled edamame to the skillet, sautéing for 5-6 minutes until tender-crisp.
Stir in the minced garlic, grated ginger, red pepper flakes, sea salt, and black pepper, cooking for 1 minute until fragrant.
Pour the sauce over the tofu and vegetables, tossing constantly for 2 minutes until the glaze thickens and coats everything evenly.
