I saw a YouTube video of a guy cooking a steak by wrapping it in aluminum foil and putting the hotel iron on top. But an iron gets a lot hotter than that warming plate, plus beef is less bad to eat undercooked.
This would probably work fine, it might be a bit slow, but a coffee pot gets plenty hot to cook chicken. My main concern would be the lack of fluid increases the chances that pot breaks.
The hot plate 100% has a safety switch that turns it off at a couple degrees above boiling. So it won’t break but it also won’t sufficiently cook the chicken with pieces this large…
"Chunky" chicken soup in a can just costs a couple dollars, you could try heating that in a coffee pot. Add some fresh cherry tomatoes and canned fruit and you have a good meal.
