I received this BBQ grill plate as a gift (note: mine was a Williams Sonoma version now discontinued) and I finally got around to using it. This grill plate works best on the BBQ and it can be used for anything you want to keep hot (ie fajitas, nachos, etc).
Here’s the link to the grill plate on Amazon.
Long story short, the nachos turned out great. The photo is coming soon.
I’ve used this a few times now and I’d still recommend it. While it’s certainly good at making nachos, it’s also good at cooking/serving sizzling fajitas. Warning: just be careful — the grill plate gets (and stays) very hot.
