In a mixing bowl, combine 1 cup of cottage cheese, 3 eggs, ½ cup of shredded Parmesan cheese, 1 cup of shredded mozzarella cheese, 1 cup of crumbled feta cheese, and the thawed and drained 10 oz package of frozen spinach.

Season the filling mixture with salt and black pepper to taste.

Mix well until all ingredients are evenly combined. Set the filling aside.

Preheat the Oven: Preheat your oven to 350°F (175°C) to ensure it's ready when the appetizers are assembled and ready for baking.

Lay out 2 sheets of phyllo dough on a clean surface.

Brush one sheet with melted butter or vegetable oil using a pastry brush.

Spread a portion of the prepared filling mixture along one edge of the phyllo sheet, leaving a small border around the edges.

Carefully roll the dough into a log, enclosing the filling as you roll.

Once rolled, gently curl the dough into a spiral shape, starting from one end and working your way around until the entire roll is formed into a spiral.

Another Option: Cut the phyllo dough sheet in half long ways and add a dollop of filling on one end and fold over the dough to make triangle shape. Either way they make a great presentation.

Place the prepared phyllo dough spirals onto a baking sheet lined with parchment paper or a silicone baking mat.

Brush the tops of the spirals with more melted butter or vegetable oil to help them brown and crisp up during baking.

Transfer the baking sheet to the preheated oven and bake the appetizers for about 30 minutes or until they are golden brown and crispy.

Once baked, remove the Spinach Feta Cheese Phyllo Dough Appetizers from the oven and allow them to cool slightly before serving.

Serve warm as a delicious appetizer or snack for your next gathering or enjoy them as a tasty treat any time of day.
