In a small bowl, add in melted butter, garlic, and Italian seasonings. Stir until combined.
Preheat skillet over medium heat. Generously brush one side of a slice of bread with the butter mixture. Place bread butter-side down onto skillet and add 1 slice of cheese.
Brush a second slice of bread with the butter mixture on one side and place butter-side up on top of sandwich. Grill until lightly browned and flip over; continue grilling until cheese is melted. Repeat with remaining 2 slices of bread, butter, and slice of cheese.
