Preheat the oven to 400°F and line a large baking sheet with parchment paper.
Chop the broccoli into florets, slice the zucchini into half-moons, and cut the carrot into thin coins.
Place the vegetables on the baking sheet, drizzle with olive oil, sprinkle with sea salt and black pepper, and toss to coat.
Roast the vegetables in the oven for 20-25 minutes until they are tender and slightly caramelized.
While the vegetables roast, press the extra firm tofu with a heavy object for 10 minutes to remove excess water, then cut into 1-inch cubes.
Heat the toasted sesame oil in a large non-stick skillet over medium-high heat and sear the tofu cubes for 8-10 minutes, turning occasionally until golden brown on all sides.
Add the minced fresh ginger and garlic to the skillet with the tofu, sautéing for 1 minute until fragrant.
Pour the tamari over the tofu and stir constantly for 1-2 minutes until the tofu is well-coated and the sauce has thickened slightly.
Remove the roasted vegetables from the oven and divide them into bowls, topping with the glazed ginger-garlic tofu.
Garnish with thinly sliced green onions before serving.
