Preheat your oven to 425°F (220°C).
Peel (if desired) and cube the sweet potato into bite-sized pieces, then toss with half the olive oil, smoked paprika, garlic powder, salt, and pepper.
Spread the sweet potato cubes on a baking sheet and roast in the oven for about 25-30 minutes until tender and lightly caramelized, stirring halfway through.
While the sweet potatoes roast, prepare quinoa according to package instructions. Usually, bring water to a boil, add quinoa, cover, and simmer for about 15 minutes. Fluff with a fork when done.
For the crispy chickpeas, rinse and drain canned chickpeas (or use pre-cooked chickpeas), pat dry, and toss with a little olive oil, salt, and pepper. Spread them on a separate baking sheet and roast in the oven for 20-25 minutes until crisp, shaking the pan occasionally.
Slice the extra-firm tofu into cubes or strips. Grill in a non-stick pan over medium heat with a slight brush of olive oil for about 4-5 minutes per side until golden and firm.
Assemble the bowl by layering the fresh spinach at the base. Add the cooked quinoa, roasted sweet potatoes, crispy chickpeas, and grilled tofu on top.
Drizzle with any remaining olive oil and season with additional salt and pepper if desired before serving.
