In reply to dry:
There are several VFs in the area. We did the Ponoch/Ponoig VF on our last trip. It's long and very steep and exposed, with an abseil descent, so possibly not suitable for a novice without much climbing experience. There are some easier ones though.
The Castellats ridge is spectacular, and the first section before you reach the dragon's back is relatively easy. According to Rowland Edwards, to do the full ridge requires the ability to solo VS in order to make reasonable progress, but you can escape before the real difficulties begin. However even the first section is very exposed in places and with bits of Diff/V Diff climbing and a couple of abseils. Rowland compares it with Crib Goch, but in my opinion it's harder and definitely more exposed, and we were glad to rope up for part of it. However most is just scrambling. I've found an archived piece I wrote about it here, although the original website is no longer available:

It made a fantastic day out, but you'll have to decide whether your companion is sufficiently experienced for it. The difficulties are at the beginning, so if they can get past that they should be OK with the rest. If they can't abseil then you might have to rope them down the descents.
The Bernia ridge can be done in two sections, the western section is easier and makes a great ridge walk with some scrambling but no real climbing.
