Toasted Bagel, Canadian Bacon, Cheese for Breakfast

My daughter Deah came up with the recipe as a filling and tasty breakfast dish. Its Bagel toasted in butter, with Canadian bacon and cheese. You need a bagel, sliced in half before the trip, with butter in a small threaded plastic container, a couple slices or a pack of Canadian bacon, and cheese slices, a couple per person, per sandwich. Bagels will last in a pack for 3 or 4 days, and the Canadian bacon will last at least as long as that.
