In a mixing bowl, combine the thawed and squeezed spinach, chopped artichokes, shredded gouda or fontina, shredded mozzarella, grated parmesan, grated garlic, and chopped basil. Mix well until all ingredients are thoroughly combined. Add a pinch of red pepper flakes if you like a bit of heat.
Take one pita and carefully open it up. Spoon a generous amount of the spinach and artichoke mixture into one side of the pita. Fold the other side over to create a pocket. Repeat this step with the remaining pitas and filling.
In a non-stick skillet, melt 1 tablespoon of salted butter over medium heat. Ensure the butter coats the bottom of the skillet evenly.
Place one stuffed pita in the skillet. Cook for about 3-4 minutes on one side, until golden brown and crispy. Carefully flip the pita using your spatula and add another tablespoon of butter to the skillet if needed. Grill the other side for another 3-4 minutes, making sure the cheese melts inside.
Remove the grilled pita from the skillet and place it on a cutting board. Repeat with the remaining pitas, adding butter to the skillet as needed. Once all pitas are grilled, slice them in half and serve warm with a drizzle of honey for dipping.
