Steps
1. Preheat the oven to 400°F (200°C).
2. Wash the sweet potato and prick it a few times with a fork. Place it on a baking sheet and roast for 45 minutes or until tender.
3. While the sweet potato is roasting, heat olive oil in a pan over medium heat.
4. Add the chopped walnuts and toast them lightly for 2-3 minutes.
5. Add chickpeas, cumin, smoked paprika, cayenne pepper, salt, and pepper. Cook for 5 minutes, stirring occasionally, until chickpeas are heated through and spices are fragrant.
6. Remove from heat and stir in fresh parsley.
7. Once the sweet potato is done, slice it open lengthwise and fluff the inside with a fork.
8. Spoon the walnut and chickpea mixture into the sweet potato.
9. Top with a dollop of Greek yogurt if desired and serve warm.
