I am looking into making my own pot meals like pot noodles (curries, chili con carne, pastas - NOT noodles) that I can just add hot water to, specifically a kettle that is extremely easy to reheat. I'm aware on how to dehydrate individual ingredients but specifically what's the process for making something like that? Any tips for rice, grains & pastas? Everything I look online for is related to hiking foods, which is as much as brilliant and guided me into the right direction, isn't what I feel I am after. I would like to make my own dehydrated pot meals, heated by a kettle exactly how pot noodle brand works (but healthier and to my own taste) i can batch and keep for the future
