Id like to use the grill to cook burgers i've tried other methods before but they never come out quite right. obviously the oven inst ideal but its all I've got. I would love any help with what I need to properly grill on my oven allowing moderate air flow and also being able to close the grill while its grilling is important to me. Thanks for reading and hope you can help me out. buying today so not sure if this is urgent or not.
