A:Answer Sure it will, but a microwave may be quicker...
It's good at heating something once the temp has been achieved. All convection style toaster ovens go thru a per-heating cycle.
I'd look for it to bake, broil to brown and cook something raw before I'd want to just reheat something - unless I was wanting to browning it better.
You'd be hard pressed to fit two dinner plates in this oven - in the open is 13" side to side, front to back it's 11-1/4" which extends out in the back wall of a radius to 13" at center, and then 5-3/4" in the open height.
