[O] Showing only subprojects in the agenda

[Wiskey 5 Alpha]

Hello all,
    I'm sure this is not as complicated as i am making it out to be, but i have tried every option i can think of.

    My org files consist of three todo states : TODO NEXT | DONE

Any TODO is a project, and it may have sub projects like so :

* TODO Make dinner

** TODO Make homemade pizza

*** NEXT roll out the crust

*** NEXT add sauce

*** NEXT add cheese

** TODO Make a side salad

*** NEXT chop lettuce

*** NEXT chop tomatos

What I would like is to have my projects list agenda show :

TODO Make homemade pizza

TODO Make side salad

Basically, my projects are any TODO that has no TODO children, but may have NEXT children.

How can i get the agenda view to only show them ?

thanks
