In a small mixing bowl, combine softened butter, garlic powder, and dried parsley. Blend until creamy and well incorporated.

Generously spread the garlic butter mixture on one side of each slice of bread.

In a non-stick skillet over medium heat, place two slices of bread butter-side down. Sprinkle half of the shredded cheese evenly over each slice. Top with remaining slices of bread, buttered sides facing up.

Cook the sandwiches for about 4-5 minutes until golden brown. Press down gently with a spatula to ensure even cooking.

Carefully flip the sandwiches and cook for another 4-5 minutes until the second side is golden brown and the cheese has melted.

Remove the sandwiches from the skillet, let them rest for a minute, then slice in half diagonally and serve immediately.
