Preparation
  1. Preheat your oven to 375°F (190°C) and lightly grease a 9x13 inch baking dish.

Assembly and Baking

  2. Sprinkle half of the shredded cheese over the vegetables, then pour the egg mixture over the vegetables and cheese.
  3. Top with the remaining cheese.
  4. Bake for 30-35 minutes, or until the casserole is set in the center and lightly golden brown on top.
