Bonjour Harjot,
Kwiziq's dictation exercises usually provide most of the vocabulary necessary to complete the exercise at the beginning before clicking on "Start the exercise". I checked this specific exercise and the vocabulary related to food is present.
If you need more help regarding food vocabulary, you can take a look at Kwiziq's vocabulary lists below (you can use the search tool included):
I hope this is helpful.
Bonne journée !
