Like probably a lot of people following special diets, I prefer to eat my own food whenever possible. I'm just seeking ideas for how to heat food in a pyrex bowl (typical meal for me is precooked rice and meat) when away from home. I know sometimes gas stations have microwaves in the area they sell convenience foods in, but in a city, these can be hard to come by.
And I think I've tried every type of contraption around (hot plate that plugs into car power outlet, self-heating type camping meal heaters, etc.), but haven't found one that works too well.
Any ideas appreciated,
