Ingredients
For the Quesadillas

• 4 large flour tortillas
• 2 cups fresh spinach, chopped
• 8 oz (225 g) mushrooms, sliced
• 1½ cups shredded mozzarella cheese
• ½ cup shredded cheddar cheese
• 2 cloves garlic, minced
• ½ small onion, finely chopped
• 1 tablespoon olive oil
• ½ teaspoon Italian seasoning
• ¼ teaspoon paprika
• ¼ teaspoon black pepper
• ¼ teaspoon salt, or to taste
• 1 tablespoon butter or olive oil, for brushing tortillas
  Optional Dipping Sauce
• ½ cup sour cream or plain Greek yogurt
• 1 tablespoon lemon juice
• 1 small garlic clove, minced
• Pinch of salt
• Chopped parsley, optional
  Instructions

1. Preheat the oven: Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
2. Cook the mushrooms: Heat 1 tablespoon olive oil in a skillet over medium heat. Add the chopped onion and sliced mushrooms. Cook for 5–7 minutes, stirring occasionally, until the mushrooms release their moisture and begin to brown.
3. Add garlic and spinach: Stir in the minced garlic and cook for 30 seconds. Add the spinach and cook for another 1–2 minutes until wilted.
4. Season the filling: Add Italian seasoning, paprika, black pepper, and salt. Stir well, then remove the pan from the heat. Let the filling cool slightly. Drain any excess liquid to keep the quesadillas crispy.
5. Prepare the tortillas: Place the tortillas on a clean surface. Sprinkle mozzarella and cheddar over one half of each tortilla.
6. Add the filling: Divide the spinach and mushroom mixture evenly among the tortillas. Add another light layer of cheese on top of the filling.
7. Fold the quesadillas: Fold each tortilla in half and press gently to secure the filling.
8. Brush with oil: Arrange the folded quesadillas on the prepared baking sheet. Lightly brush both sides with melted butter or olive oil for a golden, crispy finish.
9. Bake: Bake for 8–10 minutes, then carefully flip each quesadilla and bake for another 7–10 minutes, until golden brown and the cheese has melted.
10. Prepare the dipping sauce: Mix sour cream or Greek yogurt with lemon juice, minced garlic, and a pinch of salt. Add parsley if desired.
11. Slice and serve: Allow the quesadillas to rest for 2 minutes. Cut each into wedges and serve warm with the dipping sauce.
    Tips for Perfect Quesadillas

• Remove excess moisture: Cook the mushrooms thoroughly and drain the filling before assembling.
• Use freshly shredded cheese: It usually melts better than many pre-shredded varieties.
• Avoid overfilling: Too much filling can make the tortillas difficult to flip.
• Make them extra crispy: Bake directly on a parchment-lined baking sheet, or use a preheated baking sheet for a crispier base.
• Add more flavor: Include red pepper flakes, fresh basil, or a pinch of chili powder.
  Variations
• Extra protein: Add cooked shredded chicken or black beans.
• Mediterranean style: Add crumbled feta and chopped sun-dried tomatoes.
• Spicy version: Add jalapeños or crushed red pepper.
• Low-carb option: Use low-carb tortillas and check their baking instructions.
  Nut Information
• Tree nuts: None required.
• Peanuts: None included.
• Dairy: Contains mozzarella, cheddar, and optional sour cream or Greek yogurt.
• Gluten: Regular flour tortillas contain wheat. Use certified gluten-free tortillas if needed.
• Allergy note: Check tortilla, cheese, and sauce labels for allergen statements and cross-contact warnings.
