Step 1

Preheat the oven to 400F. Pierce each sweet potato several times with the tines of a fork. Place them in a shallow baking dish and bake until the sweet potatoes are easily pierced with a knife and cooked through, about 45-60 minutes depending on size. Remove from oven and let stand until cool enough to handle.

Step 2

While the sweet potatoes are baking, make the spanakopita topping: In a large skillet over medium heat, heat 2 tablespoons of olive oil and cook the onion until lightly golden, about 10 minutes. Stir in the spinach just to wilt. Set aside to cool. Mix in remaining ingredients and set aside until the sweet potatoes are done.

Step 3

Slice sweet potatoes lengthwise down the center to expose cooked insides, top with spanakopita mixture and serve.
