Sure thing. Grab a small charcoal grill, ditch the electric igniter, and use a chimney starter. Fill it with charcoal, light a paper cube in the bottom, and wait a few minutes for the fire to spread. Then slide the coals into the grill, set your food on the grate, and you’ve got a solid heat source without plugging anything in. Works great on a cold night shift when you need a quick bite and a bit of warmth.
