I've come to enjoy grilling sliced onions and button mushrooms while the meat is on the fire, especially when I'm making fajitas. I soak them in olive oil and give them a dash of seasoned salt, usually. I even throw on the occasional poblano or bunch of jalapenos. the only problerm is that all of these foods have a tendency to fall down into the coals and generally be a pain in the *** to manipulate without losing half of what you started with. I was wondering if they made some sort of chicken wire -esque rack or screen specifically for grilling these smaller items over charcoal. Any suggestions?
