01 - Preheat oven to 400°F (200°C). 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 tender throughout.
03 - Let sweet potatoes cool slightly. Slice each potato lengthwise and scoop out some flesh to form a cavity, leaving about 1/4 inch around the edges. Reserve half of the scooped sweet potato for filling.
04 - Drizzle olive oil inside each boat and season generously with smoked paprika, salt, and pepper.
05 - Heat 1 tablespoon olive oil in a skillet over medium heat. Sauté diced red bell pepper and chopped spinach until softened, about 2 to 3 minutes. Add half of reserved sweet potato flesh and mix to incorporate.
06 - Evenly distribute sautéed vegetable mixture into sweet potato boats, forming a well in the center of each. Crack one egg into each well.
07 - Return baking sheet to oven and bake 12 to 15 minutes, or until eggs are cooked to preferred doneness.
08 - Remove from oven. Top each boat with avocado slices, crumbled feta cheese, and chopped chives or green onions. Serve immediately while warm.
