Imaginary Expressive Object

This is my MicroPlate which is intended for people who eat leftovers.   The purpose of the object is to heat food evenly so that you don't end up overcooking one thing on a plate trying to get the rest of the food warm.   It's useful because different foods take longer to cook than others.   For example, mashed potatoes take longer than green beans since potatoes are more dense and usually drier than green beans.   The leftover cooker is in the form of a plate and can determine the density, portion, and moisture of the food in order to determine how to heat the food.

To use the  MicroPlate a person must have spacial awareness and the ability to apply pressure to a button.

Since the  MicroPlate must be able to exist in real life, we'll say that it cooks the food using microwaves.   Also that there is a lid with sections that creates compartments to separate the different microwave intensities that prevents radiation from escaping.
