Creating spinach and feta quesadillas is simple and can be accomplished with these easy steps:

1. Sauté the Spinach: In a skillet over medium heat, add olive oil and minced garlic. Sauté for about 1 minute until fragrant.
2. Add Spinach: Fold in the chopped spinach and cook until wilted, about 2-3 minutes. Season with salt and pepper to taste.
3. Mix Cheeses: In a bowl, combine the wilted spinach, crumbled feta cheese, and shredded mozzarella cheese. Mix well to incorporate.
4. Heat Tortillas: In the same skillet, place a tortilla over medium heat. Cook for about 30 seconds until warmed.
5. Add Filling: Spoon half of the spinach and cheese mixture onto one half of the tortilla.
6. Fold Tortilla: Carefully fold the tortilla over the filling to create a half-moon shape.
7. Cook Quesadilla: Cook for 2-3 minutes on each side, or until golden brown and cheese is melted.
8. Repeat: Repeat steps 4-7 with the remaining tortillas and filling.
9. Slice and Serve: Once cooked, transfer to a cutting board and slice into wedges.

These steps will guide you to create scrumptious spinach and feta quesadillas effortlessly.
