A while back, Mr. Squirrel mentioned using a plastic bag to heat chili
to avoid mess, maybe in his camper, maybe not.  I had meant to respond
with the proper way to heat chili (or any other canned food that is
wanted hot) to avoid having to clean a pot.  However, it was not Friday,
and I forgot.  Today is Friday, and I remembered.

To heat canned chili, remove the label from the can.  Put the can,
unopened, no holes punched, in a pot and cover by at least an inch above
it with water.  Bring to a boil and allow to boil a few minutes, until
the can is definitely heated through.  Remove the can from the water,
open it, and dump the chili into a dish.  Eat.

The can will not develop pressure inside as some might fear, because the
water boiling in the pot is the same temperature and pressure as the
can.  There might be a slight increase in pressure when the can is
removed from the pot, if the contents are at boiling temperature, but
not much.  A cloth or paper over the top when the can is opened will
keep any slight spray from splattering things in the vicinity.

This is quite safe.  I have done it many times.  I learned it from my
father years ago on camping trips.
