How do you  barbecue asparagus in foil?
 Chop the ends off. Take a large sheet of tinfoil, and place the asparagus in the middle of it. Gather the sides together and then bring the tops together. Don’t seal just yet. Add your olive oil, garlic, and salt and pepper. Close the pouch and gently shake, so that everything is incorporated. Peak back in the pouch to make sure the asparagus is covered with a smidge of olive oil. If not add a little more. Add the pouch to direct heat on a grill for about 20 minutes.
