If you are really trying to save energy then the microwave is excellent.
It'll steam cook (put them into a pyrex caserole dish, one with a lid) vegetables in minutes.
No loss of nutrients either.
It re-heats food quickly and efficiently. 2 minutes and those bags of rice and really hot.
You can bake a cake in a mug in two minutes as well, and it works well for gluten free ones
It'll make a quick omelette, again in a pyrex dish, that comes out clean with no added oil, in two and a half minutes, and it'll bake a big spud in six.
I didn't want a microwave, thought they were just a gimicky gadget, but Himself bought one, and I got used to it.
Then I realised that it's a really good way to cook food.
It's not the
only way I cook food, but it's far more useful than just for 'Ding Dinners'.
