Crack the eggs into a mixing bowl. Add the grated cheeses, Italian seasoning, salt and pepper. Beat together until well combined. Whilst you prepare the eggs lightly oil your waffle maker and preheat to a medium/high setting.
Spoon the egg and cheese mixture carefully into the waffle maker so that it is level and not too full. You will likely need to make these in two separate batches. You should end up with 8 small waffles or enough to provide four portions depending on your waffle maker.
Close the lid and leave for 4-5 minutes or until cooked through. This will depend on the intensity of your waffle iron but you may cook for longer as needed. The waffles should be set and golden and will crisp further on standing.
Preheat the oven to 400 degrees Fahrenheit. Once the waffles are cooked through, cover each in a thin layer of marinara. Tear the ham into bite sized pieces and arrange across the chaffles. Roughly chop the sundried tomatoes and scatter over the top. Arrange the chaffles across a shallow oven tray and bake for 5-6 minutes or until the prosciutto is crisp. Scatter with chopped fresh basil to serve.
