Menu reports are available in the Settings > Menu Reports page. It shows the number of Snacks / Breakfast / Lunch served for each child and each classroom. 

The report is using the 'Menu Type' information saved with each solid food entry. If a solid food entry is saved without a Menu Type, it won't be included in the Menu Report.

When the solid food entry is saved from a calendar entry, the menu type is automatically specified.

The list of available menu types can be customized under Settings > Customize Labels.
