1. Prepare the Vegetables
- Preheat Oven: Preheat your oven to 375°F (190°C).
- Sauté Vegetables: In a large skillet, heat the olive oil over medium heat. Add the diced onion and bell pepper, and cook until softened, about 5 minutes. Add the sliced mushrooms and cook for an additional 3-4 minutes until they are tender. Stir in the diced tomatoes and spinach. Cook for another 2-3 minutes until the spinach is wilted. Season with salt and black pepper.
2. Prepare the Egg Mixture
- Whisk Eggs: In a large bowl, whisk together the eggs and milk until well combined.
- Add Seasonings: Stir in the dried basil, dried oregano, garlic powder, and additional salt and black pepper to taste.
3. Assemble the Casserole
- Combine Ingredients: Add the sautéed vegetables to the egg mixture and stir to combine. Fold in the shredded cheddar cheese.
- Transfer to Baking Dish: Pour the mixture into a greased 9×9-inch baking dish or a similar-sized casserole dish.
4. Bake
- Bake: Bake in the preheated oven for 25-30 minutes, or until the casserole is set in the center and the top is golden brown.
5. Serve
- Cool Slightly: Allow the casserole to cool for a few minutes before slicing.
- Garnish: Garnish with chopped fresh parsley if desired.
- Enjoy: Serve warm as a main dish or a side.
