Nothing in particular against microwaves. Their effect on nutrients seems negligible, and the non-ionizing radiation is most likely not an issue. But I don't feel right being all paleo-like then heating up my lunch five days a week in a space age contraption. Fire-based cooking has been widely used for at least 100,000 years; while microwave based cooking has been widely used for 40 years. Science often ends up being imperfect in retrospect, so I figure might as well play it safe if at all possible.
Are there any alternatives that can be used in the office? There's these mug warmers that plug into a USB slot and baby bottle warmers that are more powerful. Neither is quite the contraption I'm looking for though. Basically, I've got a small container of meat and veggies, and need to heat it in something that won't risk burning down the office. Has anybody used an office food-warming hack? Alternatively, I could keep the meat unrefrigerated for four hours, but I don't know enough about food safety to do that...plus hot food tastes good.
