What do you guys use for grilling fish, vegetables, potato slices etc so that they don't fall through the grate into the fire? I usually end up making a sacrifice or two to the fire gods and I'd like to hear how everyone else does it. I really don't want to grill the fish on foil or wrap the veggies in foil. I have used a piece of mesh screen successfully, but they are of cheap quality. I think I bought a pack of them at WalMart. I'd even consider making some expanded metal grates for my Performer and Jumbo Joe. Talk to me.
