Press the tofu for 15 minutes to remove excess moisture, then cut into 1-inch cubes.
Season the tofu cubes evenly with sea salt, black pepper, and garlic powder.
Heat avocado oil in a large non-stick skillet over medium-high heat.
Add the tofu to the pan in a single layer and sear for 3-4 minutes per side until each edge is golden brown and crisp.
While tofu sears, steam the broccoli florets and edamame in a steamer basket for 5 minutes until tender-crisp.
In a small bowl, whisk together the sweet chili sauce, tamari, and sriracha.
Reduce the skillet heat to low, then add the steamed vegetables and the sauce mixture to the tofu.
Toss everything gently for 1-2 minutes until the glaze thickens and coats every piece beautifully.
Garnish with sesame seeds before serving.
