Place the tortilla in the pan and warm it for about 30 seconds per side until soft and slightly toasted

Remove the tortilla and set aside, keeping it warm

Add the spinach to the same pan and cook until wilted, stirring gently as it softens and reduces in volume

Push the spinach to one side and crack the egg into the pan

Cook the egg until the whites are set and the edges begin to firm up

Sprinkle feta cheese over the egg so it softens and slightly melts from the heat

Add a splash of water to the pan and cover briefly to create steam, helping the egg cook evenly

Transfer the egg and spinach mixture onto the warm tortilla

Fold gently and serve immediately while hot and fragrant
