Prepare your asparagus by washing it, trimming the cut end, and tossing it with the oil of your choice.
Add a generous sprinkle of salt and pepper to the oily asparagus.
Preheat your grill over medium-high heat. Clean and oil the grates (I do this with a cleaning brush and then I dip a paper towel in oil and rub it on the grates; this helps everything to not stick).
Reduce the heat to medium to medium-high, and place your asparagus on the grill so that it is crossing the grates (not parallel to them, we don't want them to fall in).
Allow the asparagus to cook 3-4 minutes and then roll or flip them over so that they can cook on the second side.
Cook an additional 3-4 minute or until bright green and tender.
Remove from the heat and place on a serving platter.
Add additional salt and pepper to taste and squeeze of fresh lemon juice if you'd like.
Serve right away.

Notes
Asparagus cooks fast, generally under 10 minutes depending on big your asparagus spears are and how hot your grill is. If you are working with other grilled goods (meat) plan on 10 minutes or less for the cook time so that everything comes off the grill hot at the same time.
The lemon is optional but it's pretty and adds a nice brightness to the dish.
