ESHOP

Hi Guys,

I am running Eshop which is great, but my client would like to do meal deals he runs a sandwich delivery shop/business.

Basically end user selects a sandwich on the same page he would then like them to select a drink and crisps and a yog and it to come to a certain price.

How would i even start doing this.

currently i have added the categories to the menu.

i do not know wordpress this is my first ever site i have designed using this platform so will need some help maybe some code.
