This is a recipe from my grandmother Ruth that I love for its simplicity. It is nothing more than a ham and cheese sandwich over which you pour some beaten eggs and milk, let it soak, and then bake. (I confess that I dressed it up a bit by adding the ham, and that my son Sam insists I should have added even more.) Any flavorful sliced melting cheese and any flavorful pork product—cooked bacon, pancetta, prosciutto, or good old-fashioned country ham—would work here. This dish can serve as a great light lunch or supper  or—because it requires so little prep—as the main attraction at a brunch for a bunch of friends.
