Preheat your oven to 400°F (200°C).
Dice the sweet potato into 1-inch cubes. Press the tofu to remove excess moisture and then cube it similarly.
In a bowl, toss the chickpeas, sweet potato, and tofu with your preferred spices (such as smoked paprika, cumin, salt, and pepper) using minimal or no oil.
Spread the chickpeas, sweet potato, and tofu evenly on a baking sheet and roast in the oven for about 25-30 minutes, or until the sweet potato is tender and the edges of the chickpeas and tofu are crisp.
While the ingredients roast, prepare the creamy lemon tahini dressing by whisking together tahini, lemon juice, minced garlic, a splash of water to reach desired consistency, and a pinch of salt and pepper.
Once roasted, assemble your bowl by layering the roasted chickpeas, sweet potato, and tofu over a bed of fresh baby spinach.
Drizzle the creamy lemon tahini dressing over the top and serve immediately.
