"Enjoy your meal" is "appréciez votre repas" in French. A standard formula is "bon appétit".
In French, you would say "ma célébrité préférée" to mean "my favorite celebrity." The word "ma" means "my," "célébrité" translates to "celebrity," and "préférée" means "favorite."
You could borrow the French and say "bon apetit", or say "Enjoy your meal." It literally means "good benefit".
We say "Bon appétit"
