In a bowl, whisk eggs with yogurt sauce, salt, and pepper until you get a homogeneous mixture.
Slice the cauliflower into thick slices, at least two centimeters wide.
Dip the cauliflower slices into the batter, ensuring each side is thoroughly coated.
Heat some oil in a skillet and cook the breaded cauliflower slices for 5 minutes on each side or until they turn golden brown and crispy.
Transfer the cauliflower slices to a baking tray, then top each slice with a slice of tomato and a slice of mozzarella cheese.
Sprinkle with oregano and grill in a preheated oven at 165°C (325°F) for 10-15 minutes or until the mozzarella melts and turns slightly golden brown.
Let your Cauliflower Parmesan Steaks rest for a while before serving.
