My grandfather actually got food delivered from Schwan's when I was little, and one of the things he always had on hand were these little ready-made hashbrowns that you just cooked up in a skillet. They were delicious, especially smothered in ketchup. :T

Other than that, probably English muffins for the win. Once or twice I also tried a couple of strawberry Pop-tarts with a slice of American cheese in the middle. BETTER THAN IT SOUNDS, REALLY.
