My favorite type of bagel is the "everything" bagel. However there never seems to be enough of the "everything" to satisfy me. Hence, I created the "Everything Shaker" (click for larger image). Now, in addition to the baked-in "everything" that comes on the bagel I can shake on a little more to the other side. Now everything is everywhere and all is good with the world.
If the holes are large enough you could also add sunflower kernels.
