They have self-heating hot pot which works with a magnesium packet sort of like MREs. They are pretty good. All the ones I've tried have sweet potato noodle and are vegetarian.
I have never heard of "self heating" noodles. What is there an energy source in the noodles? If you mean noodles like Ramen they have those. They also have more authentic noodles which are not that difficult to prepare
The companies themselves don't answer that often here but most of the noodles I've seen either need to be microwaved or have hot/boiling water added to them.
