Preheat your oven to 400°F (205°C).
In a bowl, toss the cooked chickpeas with olive oil, fresh lemon juice, chopped rosemary, thyme, salt, and pepper until evenly coated.
Spread the seasoned chickpeas on a baking sheet lined with parchment paper and roast for 25-30 minutes, stirring halfway through, until they turn crispy.
While the chickpeas roast, cut the bell peppers and broccoli into even pieces. Toss the vegetables with a little salt, pepper, and a dash of olive oil.
Place the vegetables on a separate baking sheet and roast in the oven for about 20 minutes until tender and slightly charred, stirring once or twice.
Meanwhile, press the extra-firm tofu to remove excess moisture, then cut it into cubes. If you prefer extra crispiness, you can lightly season the tofu with salt, pepper, and a drizzle of lemon juice.
Optionally, after the chickpeas are done, add the tofu cubes to the same baking sheet and return to the oven for an additional 10 minutes to warm through and develop a slight crisp on the edges.
Once everything is roasted, combine the crispy lemon-herb chickpeas, roasted vegetables, and tofu cubes on a serving dish. Give a final sprinkle of fresh herbs and a squeeze of lemon if desired, and serve warm.
