If you've gotten a meal that you weren't so keen on, you can opt out of receiving that meal in future curated packs by reviewing the meal in your Order Timeline.
Once you give a meal a Thumbs Down, you can click "Don't send me this meal again". See example below:
Please note: You will still be able to Customize Your Pack to include the meal for future orders, but we will not automatically put it in one of your packs.
This feature is currently only available for meals you have had, and you cannot preemptively opt out of meals.
