Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.

Prick the sweet potatoes several times with a fork. Place them on the prepared baking sheet and bake for 40 to 50 minutes, or until they are fork-tender.

While the sweet potatoes are roasting, combine the rinsed chickpeas, halved cherry tomatoes, diced cucumber, finely diced red onion, sliced Kalamata olives, crumbled feta cheese, chopped parsley, and optional chopped mint in a large bowl.

In a small bowl, whisk together the extra virgin olive oil, lemon juice, minced garlic, dried oregano, salt, and black pepper.

Pour the prepared dressing over the filling mixture and toss gently to coat all ingredients.

Once the sweet potatoes are cooked, allow them to cool slightly. Slice each potato lengthwise down the center, taking care not to cut all the way through. Gently fluff the interior flesh with a fork.

Generously fill each prepared sweet potato half with the Mediterranean mixture. Serve the stuffed sweet potato boats immediately.
