LOL!!! My Aunt told me a story about my Uncle, worked at Eastman Kodak for years as a welder. She said one night they carried in 2 or 3 loaves of bread, 5lbs of bacon, couple heads of lettuce and tomatoes. Said for lunch/dinner they cooked the bacon on the boilers, toasted the bread and had blt's! I've heated a can of campbell's soup in the v of the intake on a 6.0 Ford several times before to have a hot lunch, get's the soup about 140 degrees!
Worked with a guy (Ray) who used to do that. He welded up a steel version of a cast iron frying pan. For heat he used the Babbitt melting furnace (tiger torch heat source).
Ray used to make a wicked stir-fry and the aroma used to travel from the maintenance shop, up the circular stairs to the paper machines and make everyone hungry :)
He used to say "We have to work like animals but we don't have to eat like them. We can eat like MEN."
