Oh, yeah...it's easily possible to do without. I don't care for microwaves in the least, despite the fact that they are handy for quickly heating certain things. I had one....but I donated it recently to someone starting up a new home. What I use in its place are various radiant heat devices: a toaster, a small countertop radiant oven (that's good for doing a pizza slice or piece of pie), and a full sized normal oven.

No problem at all. I have not missed the microwave, and had barely ever used it anyway, even back when it was here.
