New Potato Portobello Salad

After I posted the above image as part of my What I Ate Wednesday Veg Pledge Challenge post just over a week ago, a lot of you requested the recipe, so I figured I'd better hold my end of the bargain :). Really, I keep quite close to the original Fitness magazine recipe, so I didn't want to post it if it was so similar, but seeing as the original recipe is called Warm Steak and Potato Salad, and I'm a vegetarian, I did make some substitutions! So here's the link to the original - kudos to Fitness magazine - and then my version is below.
