Preheat your oven to 400°F and line a large rimmed baking sheet with parchment paper.
Press the extra firm tofu between paper towels for 15 minutes using a heavy plate to remove excess water, then cut into 1-inch cubes.
Place the broccoli florets, sliced red bell pepper, and sugar snap peas on the baking sheet, tossing with sea salt and black pepper.
Roast the vegetables for 15 to 20 minutes until they are tender-crisp and slightly charred at the edges.
While vegetables roast, heat the toasted sesame oil in a large non-stick skillet over medium-high heat.
Add the tofu cubes to the skillet and sear for 8 to 10 minutes, turning occasionally until all sides are golden brown and crispy.
Add the minced ginger and garlic to the skillet with the tofu, sautéing for 60 seconds until the mixture becomes highly aromatic.
Pour the tamari over the tofu and toss well to ensure every cube is glazed and the liquid has slightly reduced.
Remove the roasted vegetables from the oven and add them directly into the skillet with the tofu.
Toss everything together for one final minute to combine the flavors and serve immediately while hot.
