Assemble the strata the night before, then bake it for breakfast. So easy!
In large bowl, whisk eggs, milk, cheese, soppressata, peppers, and Italian seasoning. Toss with bread cubes. Transfer to a large greased baking dish. Cover with foil and refrigerate overnight. Let stand at room temperature for about 30 minutes before baking. Meanwhile, preheat oven to 350°. Bake, covered, for 25 minutes. Remove foil and bake until browned on top, about 25 minutes more. Let cool slightly, then garnish with parsley.
