My dishwasher's name is Lynn, and while she doesn't necessarily do a very good job, she's been with the family for years:@) It's true, I have to hand wash dishes, so I like little tips that help make things easier. While we love meatloaf, it's messy... Lining the pan with aluminum foil before adding the insert is a great time (and elbow grease) saver.
You still have to wash the insert but that's the easy part.
$5 pan from Christmas Tree Shops years ago, a good purchase!
I'll spare you the pic from after I baked the meatloaf:@)
Have a happy day!
