I did some double checking, and I have all the expansion/stuff packs besides pets, fast lane stuff and seasons, but my chef is at 100% for the recipe count for which ones I do have. According to my list you are missing:
Tofu Dog (lvl 0), veggi rolls (lvl 4), spaghetti with veggie sauce (lvl 4), veggie burger (lvl 6), vegetarian grilled salmon (lvl 8 ), vegetarian dim sum (lvl 9) and vegetarian lobster thermador (lvl 10).
From what I understand (and I may be wrong) these all came with the Showtime expansion, which you seem to have since you have some of the other recipes that came with that expansion as well. None of the ones I listed are found in the bookstore though, only through leveling up. If you are not doing a dynasty or challenge with this Sim, you can use testingcheats to change her traits to give her the natural cook trait and then swap recipes with townie's.
Also, I was searching through the forum to see which expansion these recipes came with, and the ones you are missing seem to be the same ones you were missing when you posted this same problem in March. Unless you are using the same Sim now as then, it could be a glitch in your game. Something to look out for.
