In a medium non-stick skillet, heat the avocado oil over medium-high heat.
Add the ground turkey, garlic powder, and smoked paprika, breaking it up with a spatula until browned and cooked through.
Remove the turkey from the pan and set aside, then add the diced onion and red bell pepper to the same skillet, sautéing until tender.
In a small bowl, whisk together the whole egg, egg whites, sea salt, and black pepper.
Lower the heat to medium, add the spinach to the skillet with the vegetables until wilted, then pour in the egg mixture.
Gently scramble the eggs with the vegetables until just set and fluffy.
Warm the whole wheat tortilla in a separate dry pan or microwave for 15 seconds.
Spread the Greek yogurt in the center of the tortilla, then layer on the cooked turkey, the egg and vegetable scramble, and the sliced avocado.
Fold in the sides of the tortilla and roll tightly to form a burrito, then serve immediately.
