Preheat oven to 180C. Lightly grease pie plate and set aside.

In a large mixing bowl, whisk together the eggs, milk, garlic, salt and cayenne until well mixed. Stir in the cheese.

Arrange the chopped broccoli florets on the bottom of the greased baking dish. Pour the eggs mixture over the broccoli. Place in the oven and bake uncovered for 40 minutes or until the centre has set and no longer jiggly.

Let cool slightly before slicing and serving.
