Preheat grill to medium-high heat. Prepare 2 large pieces of foil.
Place half of the asparagus in the center of each foil piece. (We are making 2 foil packs because you don’t want the asparagus to overlap too much and you need room to fold the foil over.)
1 large bunch green asparagus
Drizzle the olive oil over the asparagus (1 tablespoon in each packet).
2 tablespoons olive oil
In a small bowl, whisk together the orange juice, honey and mustard. Pour it over the asparagus evenly and season with salt and pepper. Add some orange slices on top.
Fold the foil over the asparagus and seal the ends together.
Place the asparagus foil packs on the grill, close the lid and grill for 5 minutes.
Carefully flip the packs over and grill for another 5 minutes, or until the asparagus is fork-tender. The cooking time will depend on how thick the stalks are.
Open the foil packs carefully to let the steam out. Serve with the orange slices!
Notes
Honey substitute: You can substitute the honey with agave nectar to make this dish vegan.
Leftover storage: Refrigerate leftovers as soon as possible. Cover the dish with plastic wrap, or better yet, a beeswax wrap, then enjoy the grilled asparagus within 5 days.
Foil packets: I like to leave 'handles' on the ends of the foil packets to make it easier to transfer and flip them. You're basically just leaving a few inches unwrapped on each end and then twisting them or folding them over twice so that you have something to grab onto.
Reheating: Throw them on the grill again or frying pan to recapture the hot, smoky flavor.
