Directions:
- Heat olive oil in a skillet over medium heat.
- Add sliced mushrooms and cook for about 5 minutes until they are tender and slightly browned.
- Add fresh spinach leaves to the skillet and cook until wilted, about 2 minutes.
- Season with salt and pepper to taste.
- Place one tortilla in the skillet and sprinkle half of the shredded mozzarella cheese evenly over the tortilla.
- Spoon half of the cooked mushrooms and spinach mixture over the cheese.
- Top with another tortilla and press down gently.
- Cook for about 2-3 minutes on each side until the tortilla is crispy and the cheese is melted.
- Repeat the process with the remaining tortillas and filling ingredients.
- Cut each quesadilla into wedges and serve hot with salsa or Greek yoghurt on the side, if desired.
