This is quite straightforward - use Order Tags.
- Create an
Order Tag Groupthat has Order Tags for all your Soups & Salads. In General settings, set both Min and Max selected items = 1. - Create an
Order Tag Groupthat has Order Tags for all your Sides. In General settings, set both Min and Max selected items = 1. - Add all your entree products you want to have soup/salad + side into it’s own product group, and set the mapping of both of the 2 order tag groups to be for that product group (or alternatively you can explicitly specify entree products on your order tag group mapping)
