In a medium skillet over medium heat, add the olive oil and ground turkey.
Season the turkey with the sea salt, black pepper, garlic powder, and dried sage, breaking it apart with a spatula until browned and cooked through.
Add the diced red bell pepper to the skillet and sauté for 2 to 3 minutes until slightly softened.
In a small bowl, whisk together the whole egg and egg whites, then pour the mixture into the skillet with the turkey and peppers.
Stir in the spinach and scramble the mixture gently until the eggs are just set and the spinach is wilted.
Warm the whole wheat tortilla in a separate dry pan or microwave for 15 seconds until pliable.
Place the egg and sausage mixture in the center of the tortilla, fold in the sides, and roll tightly into a burrito.
Optional: Sear the seam of the burrito in the hot skillet for 30 seconds to seal it shut before serving.
