Mediterranean Quesadillas with Spinach, Feta, Mozzarella, and Red Onion are crisp flour tortillas filled with sautéed spinach, tender red onion, and two cheeses melted to perfection.
4 medium flour tortillas
1 tablespoon olive oil plus more for cooking
2 cups fresh baby spinach
1/2 small red onion thinly sliced
1 cup shredded mozzarella cheese
1/2 cup crumbled feta cheese
1/4 teaspoon dried oregano optional
Freshly ground black pepper to taste
Heat 1 tablespoon olive oil in a skillet over medium heat and sauté red onion for 3 to 4 minutes.
Add spinach and cook until wilted. Remove from heat and cool slightly.
Lay a tortilla flat and sprinkle mozzarella over half.
Add spinach and onion mixture and crumble feta on top.
Sprinkle with oregano and black pepper.
Fold tortilla in half and press gently.
Cook in a lightly oiled skillet over medium heat for 2 to 3 minutes per side until golden and melted.
Rest briefly, slice into wedges, and serve.
Do not overfill to prevent leakage.
Let filling cool slightly before assembling.
Reheat leftovers in a skillet for best texture.
