>>1772433depends what you mean by cooking. little gas burners and the like are really best for boiling water and a lot of backpacking pots and pans are made from thin metals making it tricky to cook with them as things just burn super fast.
what sort of meals do you want to cook? you can do a lot by dehydrating your own stuff at home then just using a little burner to rehydrate them. it's easier than actually trying to cook while out imo and can be just as tasty. pic related, my set up for rehydrating stuff.
