Nonstick foil makes for super easy clean-up and allows you to use less spray. If you’re using regular foil, just lightly spray the side that will be the inside of the packet with canola oil cooking spray. Regardless of what brand you use, I recommend going for the heavy-duty stuff, as it will be less likely to rip or puncture on the grill.
Foil packets can be prepped ahead and refrigerated until ready to cook. They are perfect for grilling on a gas or charcoal grill, or even over a campfire!
