WooCommerce addon for product selecting

Hello,
I need an addon to woocommerce wich will allow to make product as a set of products and a visitor can select what parts he wonts for product set to be in.

Full explain:
I’m making pizza website. There are planing to have categories like pizza, pasta, drinks and Sets.
With Sets i have problem ( i’m not nativly english and can’t find nothing on web becouse don’t know how to formule the question ). The problem is next:
When person hits Set ( 1 of the many sets ) there’s a fixed price ( ex. 25$ ) and he must choose 1 pizza, 1 desert, 1 drink.
On enothere set ( ex. 40$ ) he must choose 2 pizzas, 2 deserts and 1 large drink.
Price is fixed for sets. And to add set to cart he must first add all the items in set.. and after adding he should be able to edit thouse items.

Does enyone have plugin to suggest ?
May be there’s free solution for these ? ( i don’t think there is, but may be.. )
Would be glad to see some or may be a short name how it might be called so i could make a search by my self ( as i said i’m not nativly english and don’t know how these thing is called in english ).
