I had hotdogger on my snowmachine and heated burritos on it too. It was kinda tricky at first on how long to leave 'em in the cooker but after a few experiments an hour seemed about right. The thing eventually cracked and started rattling so it got tossed.
My buddy liked tuna fish sandmiches wrapped in tinfoil and always stuck a couple in the trunk behind the seat. After a couple hours of hard riding and bouncing around they turned into tuna ball sandmiches.
