Ingredients
  

6 large eggs

1 cup milk (or a dairy-free alternative, such as almond milk)

1 cup diced bell peppers (a mix of red, green, and yellow for color)

1 cup diced zucchini

½ cup chopped fresh spinach

½ cup diced red onion

1 cup shredded cheese (choose between sharp cheddar or creamy mozzarella)

1 teaspoon garlic powder

1 teaspoon onion powder

Salt and pepper to taste

1 cup cooked and cooled quinoa (optional for added protein and texture)

Fresh herbs for garnish (consider using parsley, chives, or basil)

Instructions
 

First, preheat your oven to 375°F (190°C). While it warms, grease a 9x13 inch baking dish with cooking spray or a drizzle of olive oil to prevent sticking.

    In a sizable mixing bowl, crack the eggs and pour in the milk. Whisk them together until you achieve a light and frothy mixture. Season this blend with garlic powder, onion powder, salt, and pepper, mixing thoroughly to ensure an even flavor.

      In your prepared baking dish, begin layering the diced bell peppers, zucchini, red onion, and chopped spinach evenly across the bottom. If you are using quinoa for an additional protein boost, sprinkle it evenly over the vegetables at this stage.

        Carefully pour the egg-milk mixture over the colorful layers, making sure it distributes evenly throughout the casserole.

          Take your shredded cheese and scatter it generously over the top, creating a delicious cheesy layer.

            Place the baking dish in your preheated oven and bake for 30-35 minutes. Watch for the eggs to set and the cheese to become a lovely golden hue. To confirm it’s ready, insert a toothpick into the center; it should come out clean when the casserole is done.

              Once baked, remove the casserole from the oven and let it cool for about 5 minutes. This will make slicing easier and help the flavors settle.

                Cut the casserole into squares and garnish with your choice of fresh herbs before serving it warm, allowing your guests to enjoy a nutritious start to their day.
