mark bittman's asparagus pesto is incredibly good and you should try it immediately.  i had some asparagus that was about to go bad in the fridge, but i didn't know how i wanted to eat it.  i imagined asparagus pesto would be good, and googled it and found this (so simple, so easy) recipe.  i ate it over pasta with peas and it was an excellent decision.  this is definitely going in my weeknight dinner rotation!
