I had a recipe that I made that was very similar, but called for boiling, then grilling the potatoes, which was kind of a PITA to grill them.  Cooking in the oven makes a lot more sense!! <img src="http://www.traveltalkonline.com/forums/images/graemlins/Thumbsup.gif" alt="" />  Mine also called for crumbled blue cheese, and making a dressing to pour over all.  This one again is much easier!  I would use red onion though, as I love red onion, especially in this type of recipe! Think I will definitely try this version, next time we have someone over!
