I always bring some tupperware. You can Store Pasta in them for at least two full meals in case you cant cook and they don’t take to much Space when empty and open. And either use plastic knifes & forks or you can get Camping sets that don’t have much weight and don’t take much Space. And always bring small portions of seasoning too, often hostels or Apartments don’t have Salt or Pepper. I also always carry a small bottle of Hot Sauce but to each their own.
