Place the turkey bacon in a cold non-stick skillet and turn the heat to medium, cooking until the bacon is browned and crispy.
Remove the bacon from the skillet and set aside on a paper towel to drain.
In the same skillet, add the fresh spinach and sauté for 1-2 minutes until just wilted, then remove and set aside.
Pour the egg whites into the skillet over medium-low heat and cook undisturbed until the edges are set, then gently scramble until fully cooked.
Warm the whole wheat tortilla in a separate dry pan for 30 seconds on each side until pliable.
Slice the avocado into thin wedges.
Layer the cooked egg whites, wilted spinach, crispy turkey bacon, and avocado slices in the center of the tortilla.
Fold the sides of the tortilla inward and roll tightly to form a wrap.
Place the wrap back in the skillet for 1 minute per side to seal the seam and create a golden, toasted exterior.
