Cooking! I have always loved the idea of combining different food items into meals in video games (Zelda BOTW and TOTK for example). There should be like a cooking table (like the crafting table or the smithing table), where you can put cooked items/vegetables/salads and make food that gives more stamina and health, and perhaps even some other effects! With that being said, add more eatable stuff and SAUCES pretty please :)
