Heat the olive oil in a large non-stick skillet over medium-high heat.
Add the ground turkey to the skillet along with the sea salt, black pepper, garlic powder, and onion powder.
Cook the turkey, breaking it up with a spatula, until it is browned and cooked through.
Stir in the rinsed black beans and baby spinach, cooking for 1-2 minutes until the spinach is fully wilted.
Lower the heat to medium and pour the egg whites directly over the turkey mixture.
Gently scramble the egg whites into the turkey and vegetables until the eggs are firm and opaque.
Warm the whole wheat tortilla in a separate dry pan or microwave for 15 seconds until pliable.
Mash the avocado and spread it across the center of the tortilla.
Spoon the turkey and egg scramble onto the avocado layer and drizzle with the salsa verde.
Fold the sides of the tortilla inward and roll tightly from the bottom to create a secure burrito.
