Preheat the fryer. In a mixing bowl, combine the cheeses, egg yolk, garlic and parsley together. Mix thoroughly.

Season the mixture with salt and pepper.

Place 1 tablespoon of the filling in the center of 16 pasta squares.

Lightly wet the edges of the pasta with water.

Place 1 pasta square on top of the filled square. Press the edges of the square firmly to seal the square. Repeat the procedure until all the squares are sealed.

Fry the squares in batches, until golden brown about 3 to 4 minutes.

Remove the ravioli from the oil and drain on a paper-lined plate.

Season the ravioli with salt and pepper.

Serve the ravioli with the warm tomato sauce and garnish with the grated Parmesan cheese.
