Preheat your oven to 375°F and line a small baking sheet with parchment paper.
Slice the top off the sourdough roll and carefully hollow out the center using a small knife, leaving a 1/2-inch thick shell to create a boat.
In a small bowl, combine the olive oil with the minced garlic and brush the mixture generously over the inside and edges of the bread boat.
In a non-stick skillet over medium heat, cook the ground turkey until browned and fully cooked, then stir in the fresh spinach until just wilted.
In a medium mixing bowl, whisk together the whole eggs, liquid egg whites, sea salt, and black pepper until well combined.
Fold the cooked turkey, spinach, and fresh parsley into the egg mixture.
Place the bread boat on the prepared baking sheet and carefully pour the egg and turkey mixture into the hollowed center.
Sprinkle the top with parmesan cheese.
Bake for 20 to 25 minutes, or until the egg filling is completely set and the bread is golden and toasted.
Allow the bread boat to rest for 5 minutes before slicing into thick pieces and serving warm.
