They're pretty much the basic breakfast sandwich (breakfast meat, egg, and cheese) but on grilled sourdough instead of a biscuit, croissant or English muffin.
The meat choices here are ham or bacon. Jack's eggs come fried and not scrambled; they're similar to McDonald's eggs on the Egg McMuffin. Breakfast Melts actually come with two slices of cheese: one American and one Swiss style.
