Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper.
Rinse and drain the chickpeas, then pat them dry with a paper towel. Toss them with a bit of salt, pepper, and a drizzle of olive oil.
Cut the firm tofu into 1-inch cubes. In a bowl, gently toss tofu with a pinch of salt and pepper.
Chop the bell pepper, zucchini, and red onion into bite-size pieces. Toss the vegetables with a light drizzle of olive oil, salt, and pepper.
Spread the chickpeas, tofu cubes, and vegetables on the baking sheet in a single layer. Roast in the preheated oven for about 25-30 minutes, stirring halfway through, until the chickpeas are crispy and the tofu and vegetables show golden edges.
While the bowl elements are roasting, prepare the tahini dressing. In a small bowl, combine tahini, lemon juice, minced garlic, and a touch of water to thin it out if necessary. Mix until smooth.
Once roasted, remove the chickpeas, tofu, and vegetables from the oven. Transfer them to a serving bowl and drizzle the creamy tahini dressing over the top.
Gently toss to combine all the flavors and serve warm. Adjust seasoning with extra salt and pepper if needed.
