There's not much to an EZGrill, the single-use aluminum pan filled with charcoal. It's impossible not to look at the thing and think "I could make that myself in about ten minutes." And maybe you can.
But can you fill it with 100% natural charcoal?* EZGrill has—enough to grill for an hour-and-a-half. Tear off the top, light a match on the starter paper, and let the coals flame down for about 15 minutes and you should be good to go.
Perhaps it's wasteful—warding people away from "unsanitary grills at the park" puts my teeth on edge, as there's no more lovely sanitizer than fire—but I can think of a few scenarios where a five-dollar little grill could be very handy. (I mentioned it was only five bucks, right?) Camping at the beach, for instance, or anywhere where fire pits are not welcome or provided. Quick outdoor cookouts at the end of a backpacking session. Or even just on the back porch for people who don't want to bother with buying a grill.
It should even be possible to recycle the grill when it's done by washing out the ashes. They're already using recycled aluminum, too.
If you want one now, you'll have to find a Winn-Dixie. If you don't know what that is (it's a southern grocery chain), then you'll just have to wait, because there's no online ordering.
* How "natural" is hard to say, and it's certainly not lump or chunk charcoal, but the manufacturer does at least note that they don't use sulfur, borax, or contaminated clay—a welcome touch, even if it will make recreating the nuance of street food a challenge that can only be solved with an infusion of carbon monoxide and Clorox.
