Heat olive oil in a large non-stick pan over medium heat and add spinach, garlic powder, and onion powder. Sauté for 1 minute until spinach begins to wilt.
Add eggs, break up the yolk with a spatula, and scramble the eggs in the pan with the spinach until cooked, about 1-2 minutes. Top with feta cheese, stir to combine, and set aside.
Lower heat to medium-low and add flour tortilla to the pan. Sprinkle half of the mozzarella cheese on one half of the tortilla. Top with the egg, spinach, and feta mixture, then top with the remaining mozzarella cheese. Fold the other half of the tortilla over.
Cook for about 90 seconds on one side until crispy and the mozzarella is melted. Flip and cook for another 90 seconds on the other side until the mozzarella is melted and the tortilla is lightly browned and crispy.
Transfer to a cutting board or plate, cut in half, and enjoy!
