This recipe from Food 52 has you make your own croutons and caesar dressing, but if you want to cheat, you could just substitute in young fresh kale leaves for the lettuce and away you go. Add croutons, dressing, parmesan. Done.
I left out the croutons (didn't have any bread) and grilled the kale for just a minute. You could do it either way, grilled or ungrilled.
