Prepare the bread slices: Lightly butter one side of each bread slice. On the unbuttered side, spread a thin layer of pesto for a touch of Italian flavor.
Garnish the croque-monsieur: On a slice of bread (pesto side), place a slice of Parma ham, add a handful of grated mozzarella and provolone, then lightly pepper. Cover with another slice of bread, buttered side out.
Cooking: Heat a frying pan over medium heat. Place the croques in the pan and cook until the cheese is melted and the bread is golden and crisp, about 3-4 minutes per side.
Serving: Serve hot, with a few fresh basil leaves to decorate.
Enjoy: Enjoy this tender croque-monsieur with a green salad for a balanced meal!
Tip: You can add a touch of heat by sprinkling with crushed red pepper!
