These disposable grill liner would make your life a lot easier, healthier and grilling more pleasant. The grills liners are made of a disposable aluminum foil that fits quite snuggly over most grilling elements as long as they have straight grill bars. These liners are 3 mils thick, so you don’t have to worry about tearing the liner when placing it on the grill. The design of the covers allows for the hot flame to sear through the cooked food, still giving that authentic grilled flavor, minus the black residue from previous use. And grilled food is extremely tasty and healthy! The smoky taste of the food and their natural flavors are unlocked when you cook over an open flame causing the fat to be drained away from the heat of the flame, allowing for a leaner piece of meat. The liners are extremely effective. They are easy to use, the taste of the food is remarkable and the clean up was easy! Just roll it into a ball and throw it in the garbage. We recommend to oil these liners before you cook or foods will stick. 12 sheets each measure 12 x 20 inch. Made in the USA.
