Garlic Bread Grilled Cheese

• 4 tbsp salted butter (see Tip)
• ⅓ cup grated Parmesan
• 1 tbsp finely chopped fresh parsley leaves (or ½ teaspoon dried parsley), optional
• 1 tsp grated garlic, from 1 to 2 cloves
• 4 slice bread (about ½-inch thick), such as white or sourdough sandwich bread
• ⅔ cup (3 ounces) low-moisture shredded mozzarella

Instructions

1. Microwave the butter in a small, microwave-safe bowl until partially melted, 10 to 15 seconds. (Alternatively, melt 2 tablespoons of butter in the nonstick skillet you will cook the sandwiches in over medium heat. Pour the melted butter over the remaining 2 tablespoons butter in a small, heatproof bowl.) Add the Parmesan, parsley and grated garlic and stir to combine. The mixture should be spreadable, not liquid.
2. Spread an even layer of the garlic butter over both sides of 2 slices of bread (about ½ tablespoon per side).Place the slices in a large nonstick skillet and top them with an even layer of mozzarella (⅓ cup each). Butter both sides of the remaining 2 slices of bread and place those on  top of the mozzarella to create 2 sandwiches.
3. Place the skillet over medium-low heat and cook until the mozzarella is mostly melted and the underside is deep golden, 3 to 4 minutes. Flip the sandwiches and continue to cook until the other side is deep golden and the cheese completely melted, 2 to 3 minutes more. Cut in half (if desired) and serve immediately.
