Pre-heat the grill to high with the deep pan plate attached. Add the olive oil and onions. Cook for 1-2 minutes stirring occasionally. Add the potatoes and cook for 5-10 minutes stirring occasionally or until the potatoes start to become soft. Turn the grill down to low 5 minutes after adding the potatoes.
Whisk the eggs together and slowly add to the deep pan plate. Close the lid and cook until golden brown, approximately a further 5-10 minutes.
