The Annapurna Introductory sounds like it fits what you're after.
The route begins in Phedi then goes through Dhampus, Landruck, Chomrong and through the beautiful rhododendron & bamboo forests then to Tadapani, Ghorepani, Poon Hill and then finishes in Naya Pul where you can get a bus to Pokhara.
I took it pretty easy and this route took me 5 days - absolutely beautiful!
