Prepare the Garlic Herb Butter:

In a small bowl, combine 4 tablespoons of softened butter, 2 teaspoons of garlic powder, 1 teaspoon of dried oregano, and 1 teaspoon of dried basil. Mix until well combined.

Assemble the Sandwiches:

Take 2 slices of sourdough bread and spread a generous layer of pizza sauce on one side of each slice. Evenly distribute 1 cup of shredded mozzarella and 1/4 cup of grated Parmesan over the pizza sauce. Top each slice with the remaining bread slices to form two sandwiches.

Butter the Bread:

Spread the garlic herb butter generously on the outside of each sandwich, ensuring both the top and bottom slices are coated.

Cook the Sandwiches:

Preheat a skillet or griddle over medium heat. Place the sandwiches in the skillet and cook for about 3-4 minutes on each side, or until the bread is golden brown and crispy and the cheese is melted and bubbly.

Add Some Heat (Optional):

If you like a bit of spice, sprinkle crushed red pepper flakes over the cheese layer before closing the sandwich.

Serve and Enjoy:

Once cooked to perfection, remove the sandwiches from the skillet and let them cool for a minute or two. Cut each sandwich in half and serve with your favorite side, like tomato soup or a fresh salad.
