Heat a skillet over medium heat and spray with cooking spray. Add spinach and cook until wilted, about 2-3 minutes.
Whisk together egg and egg whites. Pour into the pan with the wilted spinach and cook for about 2 minutes until set.
While eggs cook, warm your tortilla slightly and spread with hummus.
Place the egg mixture in the center of the tortilla, top with feta and sun-dried tomatoes.
Roll up the wrap tightly, tucking in the sides as you go.
Optional: Return wrap to the pan and cook for 1-2 minutes per side until golden brown.
