Ingredients
- 2 tablespoons extra virgin olive oil
- 1 cup red onions chopped (skip red onions if you're folling a keto diet)
- 2 cups broccoli chopped
- 3 cups mushrooms sliced or chopped
- ½ cup cherry tomatoes
- 2 cups fresh spinach
- 6 eggs
- ½ cup almond milk
- ½ teaspoon garlic powder
- ¼ teaspoon mustard powder optional
- Salt and pepper to taste
- 1 cup cheddar and mozzarella cheese mix
- Parsley for garnishing (optional)
Instructions
- Preheat oven to 325°F. Spray a casserole dish with a good coating of cooking spray, and set aside.
- In a medium skillet, add the olive oil over medium heat. Add the onions, and cook until they are soft. Then, add the rest of the veggies, and sauté until they are tender. Add this veggie mixture to the baking dish. Set aside.
- While the veggies are cooking, whisk together the eggs, almond milk, garlic powder, mustard powder, salt, and pepper in a bowl.
- Pour the egg mixture over the veggie mixture in the baking dish. Next, add the cheese.
- Cover with foil, and bake 40 minutes. Remove the foil, and cook an additional 10 minutes, or until the egg mixture is cooked through. Let it cool for 5 minutes before serving.

Notes
- To store: Leftovers can be kept in a container in the fridge for up to 5 days.
- To freeze: This casserole freezes beautifully. Once it has cooled completely, I slice it into individual portions and wrap each one tightly in plastic wrap, then place them in a freezer-safe bag or container. It keeps well in the freezer for up to 3 months.
- To reheat: When you are ready to eat, let a slice thaw overnight in the fridge, then reheat in the oven at 350°F for about 15 minutes, or microwave on medium heat for 1 to 2 minutes until warmed through.
