Ingredients

  • 4 eggs
  • 1 cup grated Parmesan cheese
  • 2 cups fresh spinach
  • 1 cup chopped carrots
  • 1 cup finely chopped onions
  • 1 cup corn
  • 1 cup cauliflower florets
  • 1 cup chopped zucchini
  • ½ cup green peas
  • Salt and pepper to taste
  • Olive oil

Instructions

  • Preheat the Oven:
    Preheat your oven to 375°F (190°C). Grease a medium-sized casserole dish with olive oil or nonstick spray.
  • Sauté the Onions and Zucchini:
    Heat 1 tablespoon of olive oil in a skillet over medium-high heat. Add the chopped onions, salt, and pepper. Sauté for 5-7 minutes until softened. Stir in the zucchini and cook for another 3-5 minutes. Remove the skillet from heat.
  • Steam the Vegetables:
    Steam the carrots, corn, cauliflower, and green peas for 5-8 minutes until tender but still slightly crisp. Alternatively, you can boil them in a pot with a small amount of water, then drain well.
  • Prepare the Egg Mixture:
    In a large mixing bowl, whisk the eggs until smooth. Add the sautéed onions and zucchini, steamed vegetables, and fresh spinach. Stir until all ingredients are evenly combined.
  • Assemble the Casserole:
    Pour the vegetable and egg mixture into the greased casserole dish, spreading it out evenly. Sprinkle the grated Parmesan cheese over the top.
  • Bake:
    Place the casserole dish in the preheated oven and bake for 15-20 minutes, or until the egg mixture is set and the top is golden brown.
  • Serve:
    Let the casserole cool for 5 minutes before slicing. Serve warm and enjoy a delightful mix of flavors and textures!
