Lay out a big sheet of industrial quality aluminum foil, pile the seasoned veggies within the middle, and high with a second sheet of foil. Fold and crimp all 4 edges tightly to seal — you need the pack hermetic so steam builds inside and does the heavy lifting. I all the time double-wrap my foil packs after studying the exhausting means {that a} single layer can tear, sending garlic oil dripping straight onto the flames (not perfect!).

Any technique works fantastically, however the foil pack is my go-to for sheer ease and consistency. Toss, seal, grill, accomplished!
