Trangias are great. You can cook almost anything in them (I've heard that souffles are even possible), and are so low-tech that there's almost nothing to break down. I even jury-rigged a sardine can as the burner once when I borrowed one that was missing this vital component. Here we have a dinner for five - chili beans, as I recall. You will notice that the corn chips (bottom left) are somewhat more fragmented than the ones straight off the supermarket shelf.
