2 pcs 15.75 x 13 Inches Oven Liner, BBQ Grill Mats.
The Oven Liner, BBQ Grill Mats is washable and reusable. Almost like a thin, flexible pan.
They are made from fiberglass fabric coated Teflon similar to what is used for non-stick pots and pans.
This means that you can cook without oils, and cleaning up is simple because everything will slide right off.
For larger grills you can use multiple mats, side by side, and for larger meals.
You can even flip one over to keep on cooking with the clean side up to preserve flavours.
