Press the tofu for 15 minutes to remove excess moisture, then cut into 1-inch cubes.
Preheat the oven to 400°F and toss the broccoli florets and sliced bell peppers with half the olive oil, sea salt, and black pepper.
Roast the vegetables on a parchment-lined baking sheet for 15-20 minutes until tender and slightly charred.
Heat the remaining olive oil in a large non-stick skillet over medium-high heat.
Add the tofu cubes to the skillet and sear for 8-10 minutes, turning occasionally until all sides are crispy and golden.
In a small bowl, whisk together the tamari, lime juice, minced garlic, and red chili flakes.
Pour the sauce mixture over the crispy tofu in the pan, tossing for 1 minute until the tofu is well-glazed.
Serve the chili-lime tofu immediately alongside the roasted broccoli and peppers.
