This is meant to be a really simple pasta dish so I kept the ingredients list pretty short, but you could easily add cherry tomatoes or wilt in some fresh spinach, add red pepper flakes if you like some spice, or fresh parsley for color. I actually was going to include fresh basil originally, but my living basil plant was well, not. You can also replace 1/4 cup or so of the water with white wine if you have a bottle open.
