Hardly use mine now I think of it. Occasionally to defrost things. And dd has a waterbottle thingy that heats up in there. Don't use it to properly 'cook' iyswim. (I have a kitchen full of bits I don't use, including a toaster though I don't eat bread. Time for a clearout I think)
Mine is a combination oven which I love, it can be used as a proper cooker, great for a couple of waffles or a pizza, heats up very quickly.
As a microwave, I make porrige heat plates, steam broccli, reheat cups of forgotton tea, defrost rolls for pack lunch, POPCORN!!! heat beans and spaggetti hoops, defrost bagels before cutting and toasting. Reheat my homemade soup, which I batch make and freeze in takeaway tubs. Occasionaly scrambled eggs, wouldn't use hob for that now.
It grills as well , hardly used grill, did bacon a couple of times as my big oven has an integral grill whcih is crap, but use my forman type grill for that now, so really never use grill at all now, don't think many people do.
