Drupal Commerce options

Hello,

I'm busy with building a webshop where people can buy products with options.

As example:
Pizza Small €5,00
- extra cheese €1,00 (optional)
- extra Meat €1,00 (optional)
----
total product price: € 7,-

I have tested the following modules:
- Commerce
- Commerce Product Attributes
- Commerce options
- Commerce Product Reference

But can't get this working. The thing I got working is the product reference link.

Product x
- subproduct a € 2,-
- subproduct b € 3,-
- subproduct c € 4,-

When select a subproduct the product price changed to the price of the subproduct.

I also tried it with Ubercart and was able to create attributes, however they don't show up within the product view. They are linked to a product in the back-end. Maybe a small bug or a missing module?
Modules I have used for this are Ubercart with the Attribute module.

I hope you can help me to get this working.
