To translate: It's also interesting that many of these dishes are made with olive oil
In the writing exercise C1 for 16/9/23 It says the correct answer uses SES : C'est aussi intéressant que beaucoup de ses plats soient préparés avec de l'huile d'olive,
I had used CESc'est aussi intéressant que beaucoup de ces plats soient cuisinés avec l'huile d'olive
I think the correct answer is "ces" translated as these plates, and especially since the review on this writing exercise discusses ce/ces.
Thanks for your thoughts.
