Step 1

Heat the butter or margarine and olive oil in small frying pan (base about 15cm in diameter) over medium-low heat and cook potato for 5 minutes. Add the ham and cook for 5 minutes or until potato is just tender.

Step 2

Preheat grill on high. Whisk the eggs, milk, Parmesan and pepper in a bowl. Pour egg mixture over potato in frying pan. Push basil leaves into mixture and then lift the potato and ham to allow egg mixture to run in between. Reduce heat to low and cook for 6-7 minutes or until frittata is almost set but the top is still runny. Place the frying pan under the preheated grill for 1 minute or until frittata is set and top is lightly browned. Loosen frittata with a spatula and slide onto serving plate.
