Heating up food with a buddy heater is great. You an get a bit of a propane taste sometimes, but not bad. Just remember that spilling something on the ceramic element can crack it. Best to heat things up in a foil container like the pics above. I usually bring a grill but I've heated up many breakfast sandwiches on my Portable Buddy. This simple bent cooling rack is about as cheap, simple and effective a way to do that as I've ever seen.
