directions

Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish.

Heat olive oil in a large skillet over medium heat. Add onions, peppers, and mushrooms. Sauté until softened.

Add garlic and cook for another 30 seconds. Push veggies to the side and add ground beef or steak. Cook until browned, seasoning with salt, pepper, and Italian seasoning.

Spread the beef and veggie mixture evenly over the base.

In a small bowl, whisk together eggs and milk, then pour over the casserole.
