Start by slicing the cauliflower lengthwise into large pieces.

In one bowl, mix the eggs and Greek yogurt, and in another, place the grated Parmesan.

Dip each cauliflower slice into the egg mixture, then coat it with the Parmesan.

Arrange the slices on a parchment-lined baking tray and top with tomato slices.

Sprinkle with additional Parmesan, season with salt and pepper, and bake for 15 minutes at 180°C (392°F).
