I adapted this easy-to-make granola from the first Harrowsmith cookbook (I made a big reduction in butter and it still works). Because we have a houseful of people, I usually double the amounts shown here. If you feed a crowd, too, make sure you have a large enough pan. My ceramic roasting pan—which is 11" x 14"—holds a double recipe comfortably. UPDATE: At an exchange student's request, we are now adding cinnamon. Good addition. The recipe has been revised accordingly.
