Begin by dicing the large tomato and finely chopping the red onion. In a medium bowl, combine the diced tomato, red onion, fresh spinach, crumbled feta, shredded mozzarella, and dried oregano. Gently toss the mixture until all ingredients are evenly distributed.

To ensure your quesadilla isn’t soggy, squeeze the fresh spinach to remove any excess moisture.

Lay out three flour tortillas on a clean and flat surface.

Divide the prepared filling evenly among the three tortillas by placing about 1/3 of the mixture on one half of each tortilla. Carefully fold each tortilla in half over the filling.

Preheat a large skillet over medium heat and add a light drizzle of oil to the pan.

Carefully place the folded quesadillas in the heated skillet. Cook each quesadilla for about 3-4 minutes on one side.

Once cooked to crispy perfection, remove the quesadillas from the skillet and let them rest for about 1 minute on a cutting board.

Cut the Cheesy Mediterranean Quesadilla into halves or triangles. Serve warm alongside refreshing cucumber salad or creamy tzatziki.
