Step 1

Preheat a grill to medium-high heat (about 400 - 425 degrees F).

Step 2

Cut 4 sheets of 14 by 12-inch heavy duty aluminum foil then lay each piece separately on countertop.

Step 3

Divide shrimp among packs near center then place asparagus to one side of the shrimp (going the long direction of the foil).

Step 4

Pour 1/2 Tbsp white wine over each. Sprinkle over garlic (1 tsp per packet) and lemon zest then season with salt and pepper.

Step 5

Divide butter pieces evenly among packets layering them over the shrimp and asparagus.

Step 6

Wrap packets in and crimp edges together then wrap ends up (don't wrap too tight - keep a little extra space inside for heat to circulate).

Step 7

Grill, sealed side upward, until shrimp has cooked through, about 9 - 10 minutes.

Step 8

Carefully unwrap then drizzle with lemon juice (or just serve with lemon wedges for spritzing) and sprinkle with parsley.
