As Ryan suggested I'm posting this as a new thread.

I'm building a website for a restaurant.
Dishes are sold separately and as part of a meal with a discount.
That's why I can't use attributes and options.
I think it will be useful to many other cases as well.

I'm presenting a form with sections - courses. In each section there are several options with radio buttons. When the user submits the form I'm creating a product kit with the selected products, add the appropriate attributes and discount and add it to the cart.

A sample form:

Main course
Meat
or
Chicken
Desert
Ice cream
Cake

ADD_TO_CART

Two great improvements could be:
- A module that build is in charge of building and displaying the form. The webform module might help allot. The only thing that is missing is to be able to dynamically populate the webform using taxonomy terms. The developer said it's on the pipeline.
- The product-kit could be virtual. It'll function and display as a usual product-kit in the cart but won't be saved to the database.
