Start with a stump (looks more like a thick chunk of firewood to me, but hey we’ll call it a stump to not argue). Use a chain saw to cut most of the way through the stump in wedge shapes. Leave the bottom intact so that your stump stays together.
Not sure what they used, I’m going to guess charcoal, but light and place in middle of stump wedges.
Heat your cast iron pan and start cooking your food of choice using the top of the stump as a mini stove top.
When done, be sure to put your stump fire out well so not to catch the yard, woods, field, etc. on fire.
