Reheating in the oven: why and how?
1. You miss out on nothing. You do risk overcooking in the Microwave, as all you need to do is reheat, so be careful with the timing

I use a glass bowl with lid, or reusable silicone lid instead of messy plastic wrap. Usually much nicer that way, as it can sweat in plastic wrap and go mushy

2.  Re-heating in the oven is not ideal for delicate food. OK for Pizza, but for food that can go tough quickly is tricky. Either use the nukelator or a medium hot skillet. The skillet will only work if there is plenty of sauce or oil
