Then add the minced garlic and cook for another minute until fragrant.
Add the fresh spinach to the skillet and stir until wilted, about 2-3 minutes.
Stir in the drained chickpeas, chopped sun-dried tomatoes, and chopped Kalamata olives. Season with salt, black pepper, and a pinch of dried oregano. Cook for another 2-3 minutes to warm through.
Remove the skillet from heat and gently fold in the crumbled feta cheese, fresh lemon juice, and chopped parsley. Adjust seasonings to taste.
Once the sweet potatoes are cool enough to handle, slice each one lengthwise down the middle. Use a fork to fluff up the flesh and scoop out a little to create more room for the filling.
Spoon the Mediterranean filling into each sweet potato half, piling it high. Optionally, sprinkle extra feta on top and return to the oven for another 5-10 minutes to heat through.
Remove from the oven, drizzle with extra virgin olive oil, garnish with fresh parsley, and serve warm.
Notes
These stuffed sweet potatoes pair well with a light salad or grilled vegetables, and can be made ahead of time.
