Place a non-stick skillet over medium-high heat and add the ground turkey.
Season the turkey with sea salt, black pepper, and garlic powder, breaking it apart with a spatula until browned and cooked through.
Add the black beans and baby spinach to the skillet, stirring for 1-2 minutes until the spinach is completely wilted.
In a small bowl, whisk together the whole egg and egg whites until combined.
Reduce the heat to medium and pour the egg mixture into the skillet with the turkey and vegetables.
Gently scramble the eggs with the mixture until they are set and fluffy.
Warm the grain-free tortilla in a separate dry pan for 30 seconds per side until pliable.
Spread the mashed avocado in the center of the tortilla, then top with the egg and sausage scramble.
Drizzle with salsa, fold in the sides, and roll the tortilla tightly into a burrito.
