Follow these simple steps to make your Spinach and Feta Quesadillas:

1. Prepare Spinach: In a large skillet, heat the olive oil over medium heat. Add the chopped spinach and sauté for about 2-3 minutes until wilted.
2. Mix Filling: In a mixing bowl, combine the sautéed spinach, feta cheese, mozzarella cheese, garlic powder, salt, and pepper. Stir well until everything is mixed.
3. Heat Tortillas: In the same skillet, slightly warm each tortilla one at a time, about 30 seconds on each side, to make them pliable.
4. Fill Tortillas: Place a generous portion of the spinach and cheese mixture on one half of each tortilla.
5. Fold: Fold the tortilla over to create a half-moon shape, gently pressing down to secure the filling.
6. Cook Quesadillas: In the skillet, add a little more olive oil if needed. Cook each quesadilla for about 3-4 minutes on one side until golden brown, then flip and cook the other side for an additional 2-3 minutes.
7. Repeat: Continue this process with remaining tortillas and filling until all quesadillas are cooked.
8. Slice and Serve: Remove from heat, let cool slightly, and then cut each quesadilla into wedges.

These easy-to-follow instructions will guide you through the process of making these delicious quesadillas effortlessly.
