Mediterranean Quesadillas with Spinach, Feta, Mozzarella, and Red Onion combine creamy cheese, tender greens, and sweet onion inside golden, crisp tortillas for a satisfying lunch or light dinner.
4 medium flour tortillas
1 tablespoon olive oil, divided
2 cups fresh baby spinach
1/2 medium red onion, thinly sliced
1 cup shredded low-moisture mozzarella
1/2 cup crumbled feta cheese
1/2 teaspoon dried oregano
1/4 teaspoon freshly ground black pepper
Heat half of the olive oil in a skillet over medium heat. Add sliced red onion and cook for 3 to 4 minutes until softened.
Add spinach to the skillet and cook until wilted, about 2 to 3 minutes. Remove from heat and allow to cool slightly.
In a bowl, combine mozzarella, feta, oregano, and black pepper. Stir in the spinach and onion mixture.
Place a tortilla on a flat surface. Spread filling evenly over half of the tortilla, leaving a small border. Fold the tortilla over.
Heat remaining olive oil in the skillet. Cook the folded tortilla for 2 to 3 minutes per side until golden and crisp and the cheese has melted.
Transfer to a cutting board, rest briefly, then slice into wedges. Repeat with remaining tortillas and filling.
