Preheat the oven or toaster oven to 375 degrees F. Line a small sheet pan with parchment paper or foil and set aside.
Poke the sweet potatoes all over with a fork. Microwave the sweet potatoes until they feel soft when gently squeezed, 5 to 6 minutes. Allow to cool slightly. Cut in half lengthwise, creating oblong shapes. Select the nicest two halves for using as the base. Scoop them with a teaspoon, leaving a 1/4-inch border and placing the pulp in a mixing bowl. Place the bases on the lined sheet pan. Scoop out the other two halves completely and add the pulp to the mixing bowl, discarding the skins. Add the white scallions, coconut oil, paprika, 1/8 teaspoon salt and some freshly ground black pepper. Mash with a fork until smooth. Using a teaspoon, fill the two bases with the mashed sweet potatoes. Smooth with the back of the spoon. Sprinkle with feta and bake until the cheese begins to brown, about 17 minutes.
Sprinkle with the green scallions and additional smoked paprika.
If you want to get fancy, add the seasoned mashed potato mixture to a small plastic bag. Cut 1/4 inch from a bottom corner, and pipe the potatoes into the skins in whatever pattern you like.
