Spray a large baking dish with cooking spray to prevent sticking. In a skillet, cook the bulk pork sausage over medium heat until browned. Add the chopped red and yellow bell peppers, onion, and minced garlic, cooking until softened. Stir in the dried oregano and fresh spinach until wilted.
In a mixing bowl, whisk together the eggs, whole milk, Dijon mustard, salt, and black pepper. Layer half of the frozen diced hash browns in the baking dish, then add the sausage mixture and sprinkle with Monterey Jack cheese. Pour the egg mixture evenly over the top before adding the remainder of the hash browns.
