Hello ALL! I'm  new the square biz and also new to the food truck world! So please take it easy on ME lol!!

So my question is I want to be able to add a size and flavors on one ticket. I.E you order a Small and you get  your choice of 3 flavors, toppings and/or even Ice cream added how can I customzie this ticket?
