The Klaviyo card has a Catalog section:

1. Click Go to link next to Klaviyo Setup Page to open Klaviyo's catalog page.
2. Copy the Catalog link shown on the card using the copy button next to it (it is a unique, signed feed address on your Sprwt site).
3. In Klaviyo, add a new catalog source that fetches that link.

The feed lists every active meal (name, description, image, price, link to the meal page) and every active pack. It only works while the Klaviyo module is enabled; otherwise the link returns Klaviyo module not active. Klaviyo re-reads the feed on its own schedule, so newly added meals appear after its next fetch.
