Heat the grill to its highest setting. Heat the butter and oil in a large 20- 25 cm ovenproof frying pan over a medium-high heat. Add the mushrooms and fry for 5-6 mins, until mostly softened, then add the garlic. Season well with black pepper and salt before adding the spinach and the ham. Cook together until the spinach has wilted. This won't take more than a minute.

Reduce the heat and pour over the eggs. Coat the vegies and ham in the egg before leaving to cook, undisturbed for 5-6 mins until the eggs are mostly set. Sprinkle over the cheese and put under the grill for 2-4 mins. Serve hot or cold with a big green salad.
