Press the extra firm tofu for at least 15 minutes to remove excess moisture, then cut into 1-inch uniform cubes.
In a medium bowl, toss the tofu cubes with arrowroot powder, sea salt, and black pepper until each piece is evenly coated.
Heat avocado oil in a large non-stick skillet or wok over medium-high heat and sear the tofu until golden and crispy on all sides.
Add the broccoli florets and shelled edamame to the pan with a small splash of water, covering with a lid for 2 minutes to lightly steam.
In a small jar or bowl, whisk together the tamari, toasted sesame oil, chili garlic sauce, grated ginger, and minced garlic.
Remove the lid and pour the sauce over the tofu and vegetables, stirring constantly for 1-2 minutes until the glaze thickens and coats the ingredients.
Remove from heat immediately and serve while the tofu is hot and the broccoli is vibrant green.
