Preheat your oven to 400°F (200°C). Wash and dry the sweet potatoes, then prick them several times with a fork.
Rub 1 tablespoon of olive oil over the sweet potatoes and season with salt. Place them on a baking sheet.
Roast the sweet potatoes for 45-55 minutes, or until they're tender when pierced with a fork.
While the potatoes are roasting, prepare the chickpeas. Toss them with 2 tablespoons olive oil, cumin, paprika, garlic powder, salt, and pepper.
Spread the seasoned chickpeas on another baking sheet and roast for 20-25 minutes, shaking the pan halfway through, until they're crispy.
Make the tahini sauce by whisking together tahini, lemon juice, minced garlic, and water until smooth. Add water gradually to achieve your desired consistency. Season with salt.
Once the potatoes are done, split them lengthwise and fluff the inside with a fork.
Top each potato with the crispy chickpeas, drizzle with tahini sauce, and garnish with your chosen toppings.
