Place the turkey bacon in a cold non-stick skillet and turn heat to medium, cooking until browned and crispy on both sides.
Remove the bacon and set aside on a paper towel, then wipe the skillet clean.
Add the olive oil to the skillet over medium heat and sauté the fresh spinach until just wilted.
Pour the egg whites into the skillet with the spinach and scramble gently until fully cooked and opaque.
Warm the whole wheat tortilla in a separate pan or microwave for 15 seconds to make it pliable.
Layer the scrambled egg whites, spinach, crispy turkey bacon, sliced avocado, and crumbled feta cheese in the center of the tortilla.
Fold the sides of the tortilla inward and roll tightly to form a wrap.
Optional: Place the wrap back in the hot skillet for 30 seconds per side to seal the seam and add a light golden crunch.
