Rinse and dry 1 medium sweet potato, then cut it in half lengthwise. Rub the cut sides with 1/2 teaspoon light olive oil and sprinkle lightly with a pinch of coarse sea salt.
Oven Method: Preheat the oven to 400°F and line a baking sheet with parchment paper. Place the sweet potato halves cut-side down and bake for 30 to 40 minutes, until a fork slides easily through the center.
Air Fryer Method: Place the sweet potato halves cut-side down on parchment trimmed just slightly larger than the potato. Air fry at 380°F for 25 to 30 minutes, until fork tender and soft all the way through.
Heat a skillet over medium heat with 1 teaspoon light olive oil. Add 1 pound ground turkey and break it up with a spatula. Season with 1 tablespoon Worcestershire sauce, 1 teaspoon salt, 1 teaspoon garlic powder, 1 teaspoon dried sage, 1 teaspoon dried rosemary, 1 teaspoon paprika, 1/2 teaspoon dried thyme, and 1/8 teaspoon maple extract if using.Cook for 7 to 9 minutes, stirring occasionally, until the turkey is fully cooked and no longer pink. Transfer to a plate lined with a paper towel. Lower the heat to low or medium-low and add 1 teaspoon butter to the skillet. Crack in 2 large eggs and add 2 to 3 small pinches of salt. Stir gently with a silicone spatula, cooking slowly until the eggs are just set and still slightly glossy, about 3 to 4 minutes. Remove from heat before they look fully done.
Place one sweet potato half on a plate and gently fluff the center with a fork. Add 2 tablespoons plain Greek yogurt, 1 scrambled egg, about 1/4 cup cooked turkey sausage, 1 to 2 ounces shredded cheddar cheese, and 1 to 2 tablespoons sliced green onion. Serve warm.
