Just reheating my pizza

Keep the iron on delicates, duty cycle much higher and the breaker will trip before the middle is warm.

Alternatively you could plug the dryer somewhere else, or use a toaster oven.

Just use tools that are made for food. Put a pan on the stove and use it like a hot plate. Heat upsidedown, but not till the cheese melts, then flip and heat from the base.
The surroundings indicate that they are in a hotel, and do not have a stove. And likely not a microwave either. Hence this setup.
