Mince the onions and soak them in a cup of water to mellow them out a bit.
Wash and trim the tough ends from the asparagus. I like to simply bend them towards the bottom and let them snap – this will always eliminate any of the tough stem.
Oil the asparagus and mix by hand to cover them, and season with salt and pepper or Cavender’s.
Broil or grill the asparagus until lightly browned and tender.
While broiling, mix up the vinaigrette
To serve, lay out the cooked asparagus on the serving bowl or tray. Drizzle with the vinaigrette and sprinkle with Parmesan cheese.
Notes
If you would prefer use shallots (the original recipe calls for them) you can replace the onion and garlic with one or two finely minced shallots.
