Heat a large non-stick skillet over medium heat and add the avocado oil.
Place the turkey bacon slices in the pan and cook for 3-4 minutes per side until they reach a deep golden brown and are crispy.
Remove the bacon and set aside on a paper towel, leaving any residual oil in the pan.
In a small bowl, whisk together the whole egg, egg whites, sea salt, and black pepper until well combined.
Add the baby spinach to the skillet and sauté for 1 minute until just wilted, then spread it evenly across the pan.
Pour the egg mixture over the spinach and immediately place the wheat tortilla directly on top of the liquid eggs, pressing down gently.
Cook for 2-3 minutes until the eggs are set and attached to the tortilla, then carefully flip the entire tortilla and egg disk over.
Crumble the crispy turkey bacon and feta cheese over one half of the eggs, then fold the tortilla in half to create a semi-circle.
Press down with a spatula and toast for 1 minute per side until the tortilla is golden and the cheese is slightly softened.
