In a medium bowl, combine cottage cheese, pizza sauce, shredded mozzarella, and Italian seasoning. Stir until well blended. Add optional seasonings if desired.

Spread a thin layer of butter on one side of each slice of bread.

Place one slice of bread butter-side down, spread cottage cheese mixture over it, and top with the second slice, butter-side up.

Preheat a skillet over medium heat and cook the sandwich for 3–4 minutes on each side until golden brown.

Remove from skillet, let rest for a minute, then slice and serve immediately with pizza sauce for dipping.
