Spread the cream cheese on one side of the tortilla. Set aside.
Heat the oil in a non-stick skillet over medium heat. Add the sun-dried tomatoes and spinach and cook, stirring, until the spinach has just wilted, 2-3 minutes. Transfer to a plate and set aside.
Spray the skillet with nonstick spray and add the egg whites, cook, scrambling the eggs with a rubber spatula, until just set, about 2 minutes. Transfer to a plate and set aside.
Spread the spinach cream cheese mixture over the tortilla, keeping it mainly in the center 1/3 portion.
Next add the egg white, then add the feta. Fold the tortilla like a burrito.
Add the wrap back into the pan and heat both sides over medium-high heat until lightly golden. This will help it hold its shape and warm the tortilla nicely.
