Prepare the Cream Cheese Filling:

1. Soften the Cream Cheese: If the cream cheese isn’t already softened, microwave it for about 10-15 seconds or leave it at room temperature for a while. This will help you mix it more easily.
2. Mix the Cheese Filling: In a bowl, combine the softened cream cheese with shredded mozzarella and cheddar cheese. Add garlic powder, dried herbs (if using), and a pinch of salt and pepper. Mix until smooth and well combined.

Assemble the Mini Sandwiches:

3. Prepare the Bread: Lay out the bread slices on a clean surface. If you prefer smaller sandwiches, you can use a cookie cutter to cut the bread into circles or squares.
4. Spread the Cheese Mixture: Spread a generous layer of the cream cheese mixture on one side of each slice of bread. Be sure to cover it evenly, but don’t overstuff, as the cheese will melt and spread while cooking.
5. Assemble the Sandwiches: Place the other slice of bread on top of the cheese-covered bread to form a sandwich. Press down gently to seal the edges.

Grill the Sandwiches:

6. Butter the Bread: Brush the outside of each sandwich with the melted butter. This will give you that golden-brown, crispy exterior.
7. Grill the Sandwiches: Heat a skillet or griddle over medium heat. Once the pan is hot, place the sandwiches in the skillet. Grill each side for 2-3 minutes or until golden brown and crispy, flipping gently with a spatula. Be sure to keep an eye on them to avoid burning.
8. Serve Immediately: Once the sandwiches are crispy and golden on both sides, remove them from the pan and place them on a plate. Let them cool for a minute before serving.

Cut and Serve:

9. Cut the Sandwiches: Depending on your preference, you can cut the sandwiches into halves, quarters, or even smaller bite-sized pieces for a more appetizer-style presentation.
10. Garnish (Optional): If you’d like to add some freshness, garnish the mini sandwiches with a few sprigs of fresh herbs, like parsley or arugula.
