This sandwich improves if it has a chance to sit for awhile, so make it at least an hour in advance. The bread will soften slightly, and the flavors will mix, mingle and really come together. Though the particular bitterness of broccoli rabe is especially good here, you could use any hearty greens, really—think leftover steamed or sauteed broccoli, spinach, chard or kale. This combo also makes a mighty fine grilled cheese...just sayin’.
