Although a classic croque-monsieur is served with a sauce Mornay, this is a simpler version, with snipped fresh chives for garnish. This recipe assumes the use of an electric panini press.
4 slices white sourdough bread
4 ounces Gruyère cheese, grated or very thinly sliced
4 ounces Black Forest ham, very thinly sliced
2 tablespoons chives, snipped with a pair of scissors
