London, April 30 : Busy office workers will no longer have to depend on a microwave to rustle up a hot snack, all thanks to a food tin that warms up its contents.
The Hotcan meal, which costs 3.99-pounds, includes beef casserole, vegetable curry and an all-day breakfast.
Hotcans, based in Chesterfield, Derbys, is also developing a new range of pasta, curry and vegetarian dishes.
The 14oz cans generate heat by mixing water and limestone when a seal on the top is broken.
And it takes no more than 12 minutes to heat up the food.
