Finding something you like on amazon and then looking through recommendations on that page can definitely be helpful. I would definitely try some light novels many of them have a lot more depth than one would think. It also depends a lot on what you like from sub genre/ story elements. Do you like Super overpowered main character? (Rise of the Cheat Potion Maker and kuma kuma kuma bear) Do you like intricate cooking details? (Campfire Cooking in Another World with My Absurd Skill) Crafting? (Dahlia in Bloom) Also depends what gender you like the MC to be and how much if any romance your looking for. I would definitely suggest Ascendance of a Bookworm though it does get more action here and there after a few books.

you can find a lot of these on amazon (kindle ebooks is my preference) if you look around the kindle store especially if you don't mind translated Japanese light novels which have many slice of life stories even when they also have just a hint of adventure. You can also peruse the website Royalroad where people upload stories they are writing chapter by chapter there are a lot of fun series of all genre there.
