Making the Cheesy Mediterranean Quesadilla is simple and enjoyable. Follow these easy steps:

1. Prepare the Filling: In a large bowl, combine the chopped spinach, diced tomatoes, sliced black olives, crumbled feta cheese, and shredded mozzarella cheese. Add the chopped red onion, olive oil, dried oregano, garlic powder, salt, and pepper. Mix well to combine.

2. Heat the Pan: Place a non-stick skillet over medium heat and allow it to warm up for a minute.

3. Assemble the Quesadilla: Place one tortilla in the skillet. Evenly spread a generous portion of the filling on one half of the tortilla, then fold the other half over the filling to create a half-moon shape.

4. Cook the Quesadilla: Cook for about 3-4 minutes on one side or until it turns golden brown and crispy. Carefully flip the quesadilla and cook for an additional 3-4 minutes on the other side.

5. Check for Melted Cheese: Ensure the cheese is melted and the filling is heated through before removing the quesadilla from the skillet.

6. Repeat: Repeat the process with the remaining tortillas and filling.

7. Slice and Serve: Once all quesadillas are cooked, slice them into wedges and arrange them on a serving platter.
