Whisk the egg whites (and egg yolk, if using) in a small bowl until combined. Set aside.
Heat the oil in a large skillet set over medium heat.
Once hot, add the spinach to the skillet and sauté until wilted, about 2-3 minutes.
Add the sun dried tomatoes, garlic, salt, and pepper to the spinach. Mix well and sauté for an additional minute.
In the skillet, form a circle (about 10 inches in diameter) with all of the sautéed veggies.
Pour the whisked egg mixture carefully over the veggies in the skillet. Use a spatula to keep the circular shape as best as possible.
Sprinkle Italian seasoning over the eggs.Â
Let the eggs cook for 3-4 minutes. While the eggs cook, use a spatula to gently pull up the edges of the circle (to make sure the ingredients aren't sticking to the pan). You'll eventually flip the egg circle in one piece.
Sprinkle the feta cheese over the eggs and place the tortilla on top.
Use a plate or a large spatula to carefully flip the eggs and tortilla over so the tortilla is down in the pan.Â
Let the tortilla heat for 30 seconds. With the tortilla and eggs still in the pan, begin folding the wrap. First, fold the bottom third of the tortilla away from you over the eggs. Then, fold each side inward, creating an open envelope shape.
Press on the folded edges of the tortilla with a spatula for 10-15 seconds while the bottom of the wrap browns.Â
Carefully flip the wrap over and continue cooking the wrap so the folded edges brown, about 1-2 more minutes.
Remove the wrap from the pan and enjoy.
