Press tofu for 15 minutes to remove excess moisture, then cut into 1-inch cubes.
In a bowl, toss tofu with cornstarch, sea salt, and black pepper until evenly coated.
Whisk together tamari, chili garlic sauce, rice vinegar, minced garlic, and grated ginger in a small jar.
Heat sesame oil in a large non-stick skillet over medium-high heat.
Add tofu and cook for 8-10 minutes, turning occasionally until all sides are golden and crispy.
Remove tofu from the pan and set aside.
In the same pan, add broccoli, bell pepper, and edamame with a splash of water; cover and steam for 3 minutes.
Return tofu to the pan and pour the sauce over the mixture.
Toss everything together for 1-2 minutes until the sauce thickens and coats the ingredients beautifully.
