Make a foil packet

How to Make a Foil Pack for Grilled Asparagus?

Folding a foil pack for grilling purposes is easy. With the tips and tricks mentioned below, you will be able to make an efficient foil pack in no time.

Cut a large sheet of heavy-duty aluminum foil. If you are using standard foil, use two layers to be extra safe in case one tears up.
If the foil is not non-stick, note that the dull side is non-stick.
Spray olive oil on the foil and put about a pound of asparagus spears on the sheet.
Use hands to toss the veggie and make sure it is coated in oil to avoid sticking.

If needed, you can also peel off the bottom skin of the spears using a peeler or a sharp knife.
