Roasted Salmon Nicoise Platter

I don't watch much tv, but for some reason one day, I happened to see The Barefoot Contessa prepare this dish.
Originally, I was just going to use the recipe for the salmon since we love fish and eat it all the time, but then I saw some cool looking purple potatoes at the store and decided I would go ahead and do the whole platter.
When Ina made this dish she was preparing for 12 people, so I only prepared 1/3 of the recipe.

I found fresh wild sockeye salmon at the fish counter and was really excited about it. The salmon was amazing! Best salmon I have tasted. It was soo good.
I reduced the oil in the marinade and the vinaigrette because I always do that when I make a vinaigrette or marinade and I don't feel that it takes away from the overall results.

My kids really liked this meal. I served it on the platter and everyone was able to take what they wanted using a pair of tongs. 1 of my kids didn't appreciate the watercress because it was "spicy".
This was a hit. Very delicious.
