Galley allows you to list the sub-ingredients of your purchased items via a vendor item's "Ingredient List." These ingredients will appear on your nutrition labels.
To access a given vendor item's ingredient list, navigate to the vendor item's page. This can be done via the "Vendors" catalog, or by going to the "Vendor Items" section for the associated ingredient.
Once in the vendor item's page, find the "Ingredient List" text box. Then, list all of the item's sub-ingredients.
The items listed will then appear in your nutrition labels surrounded by brackets [ ].
