In a small bowl, combine the egg, egg whites, salt and pepper and whisk together until thoroughly blended and beaten.

Spray a medium skillet with cooking spray and heat over medium-high heat. Once heated, add the egg mixture to the pan. Use a spatula to push the eggs from all around the edges into the center so that the set eggs are pushed into the middle and the egg liquid seeps back to the edges of the pan. When the edges are set and the center is getting there, add a few drops of hummus down the center of the omelet, then spread the hummus a bit with the back of a spoon. Add most of the Feta over the hummus. Reserve a small amount for the topping.

Fold each side of the omelet over the center. Sprinkle the fresh cilantro and diced red pepper over the top of the omelet along with any remaining Feta and serve.
