Quiche in Baking Dish:

  1. Preheat the oven to 175 degrees Celcius. Spray a 9 x 13-inch baking dish with cooking spray. Set aside.
  2. Melt the butter in a medium skillet over medium heat. Add the onion, bell pepper, zucchini and mushroom, stirring occasionally until softened (about 2 to 3 minutes). Transfer the veggies to the sprayed baking dish.
  3. Add the spinach to the skillet and cook for about 1 minute, until it wilts slightly. DO NOT overcook. Transfer spinach to the baking dish.
  4. Add the grated cheese of your choice and stir to mix.
  5. In a large bowl, whisk together the sour cream and heavy cream until smooth. Add eggs, salt and pepper to the bowl, and whisk until well combined. Pour the egg mixture into the baking dish and stir gently to evenly distribute the veggies and cheese. Lay all the halved tomatoes on top of the egg mixture.
  6. Cover with foil and bake for 45 minutes. Uncover and bake for 10 to 15 more minutes, until eggs are set. Serve warm or at room temperature.
