In an isekai setting, the character has to adapt to a new environment for survival. With the focus on'meshi', it may explore different kinds of food from the isekai world, like strange fruits, magical beasts that can be cooked, etc. This combination makes it stand out from other novels in the genre.
I'm not sure specifically as I haven't read it in full. But usually in an isekai novel, there is a protagonist who gets transported to the other world. In this 'isekai survival meshi novel', it could be someone who has a particular interest or skill related to food or survival.
