Preheat your oven to 375°F (190°C) and line a small baking sheet with parchment paper.
In a medium mixing bowl, combine the whole wheat flour, baking powder, and a pinch of the sea salt.
Add the non-fat Greek yogurt to the flour mixture and stir until a soft dough forms, then use your hands to shape it into one thick, round biscuit.
Place the biscuit on the prepared baking sheet and bake for 12-15 minutes until the top is golden brown and a toothpick comes out clean.
While the biscuit bakes, combine the ground turkey in a bowl with the dried sage, garlic powder, black pepper, and the remaining sea salt.
Form the turkey mixture into a wide, flat patty and cook in a skillet with olive oil over medium heat for 4-5 minutes per side until browned and cooked through.
Crack the eggs into a lightly greased ramekin or small oven-safe dish and place in the oven alongside the biscuit for the final 8-10 minutes of cooking until the whites are set but the yolks are still jammy.
Slice the warm biscuit in half, place the turkey sausage patty on the bottom half, top with the baked eggs, and close the sandwich to serve.
