01 - Preheat oven to 400°F. Wash and scrub sweet potatoes thoroughly, then pierce each several times with a fork.
02 - Arrange sweet potatoes on a parchment-lined baking sheet. Bake for 40 to 45 minutes until fully tender.
03 - Let sweet potatoes cool slightly. Cut each in half lengthwise and gently scoop out some of the center flesh, leaving about 1/4 inch border. Reserve the scooped flesh for later use.
04 - Drizzle olive oil into the hollowed sweet potato halves. Sprinkle smoked paprika, salt, and black pepper evenly over each.
05 - Heat 1 tablespoon olive oil in a skillet over medium heat. Sauté diced red bell pepper and chopped spinach for 2 to 3 minutes, until softened. Stir in half of the reserved sweet potato flesh and combine well.
06 - Distribute the sautéed vegetable mixture between sweet potato boats, creating a well in the center of each. Crack one egg into the center of each prepared boat.
07 - Return filled sweet potato boats to the oven. Bake for 12 to 15 minutes, or until egg whites are just set and yolks are cooked to preference.
08 - Remove sweet potato boats from oven. Top with sliced avocado, crumbled feta cheese, and chopped chives or green onions. Serve warm.
