Put a griddle pan over a gentle heat to warm. Take the gluten free bread and make two sandwiches, layering up the prosciutto, cheese, red capsicum/pepper and pesto for the filling. Brush the outsides of the bread with oil.
Put the sandwiches on the griddle and cook for about 1 minute each side – press down firmly with a metal spatula so they flatten and become golden and ridged by the griddle. Eat while deliciously hot and melted.
