The best way to Make Grilled Peppers and Onions in Foil

Lay out a big sheet of professional quality aluminum foil, pile the seasoned veggies within the heart, and prime 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 onerous approach {that a} single layer can tear, sending garlic oil dripping straight onto the flames (not ultimate!).
