Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper or use a non-stick spray.
Pat the tofu dry and cut it into cubes. In a bowl, toss the tofu with a pinch of salt, smoked paprika, and a light spray of non-stick oil. Spread the tofu on half of the baking sheet.
Drain and rinse the chickpeas, then pat them dry with a paper towel. Toss the chickpeas with cumin, smoked paprika, salt, and pepper, and spread them on the other half of the baking sheet.
Chop the broccoli, red bell pepper, zucchini, and red onion into bite-sized pieces. In a bowl, lightly season the vegetables with salt, pepper, and a light mist of non-stick oil if desired.
Place the vegetables on the baking sheet alongside the tofu and chickpeas. Roast everything in the oven for about 20-25 minutes, turning halfway through, until the tofu is golden, chickpeas are crispy, and vegetables are tender with slight char edges.
While the tofu and vegetables roast, prepare 1/2 cup of cooked quinoa according to package instructions if not already prepared.
In a small bowl, whisk together the tahini with a splash of water and a pinch of salt to create a light drizzle.
To assemble the Buddha bowl, layer the quinoa at the base of a bowl, then add the roasted chickpeas, tofu, and vegetables.
Drizzle the tahini dressing over the bowl, and serve warm.
