In a small skillet over medium heat, add the avocado oil and ground turkey, breaking it apart until browned and cooked through.
Add the diced red onion and bell pepper to the skillet, sautéing for 3-4 minutes until the vegetables are tender and fragrant.
Whisk the whole egg and egg whites together in a bowl with sea salt, black pepper, and garlic powder.
Pour the egg mixture into the skillet with the turkey and vegetables, stirring gently until the eggs are just set.
Stir in the black beans and baby spinach, allowing the spinach to wilt slightly from the residual heat.
Warm the whole wheat tortilla in a separate dry pan for 30 seconds per side until pliable and slightly charred.
Spread the salsa verde and sliced avocado onto the center of the tortilla, then top with the egg and turkey scramble.
Fold in the sides of the tortilla and roll tightly to form a burrito, then serve immediately.
