Salade Nicoise

I always thought that it would be really cool to have a Salade Nicoise in Nice, alas, I've never been to Nice, but I have been to Paris and was so happy to see this on the menu at a small cafe at the foot of Sacre Coeur. We had just got off one subway stop BEFORE Sacre Coeur and ended up in a part of Paris that we couldn't seem to make out from the tourist map. Apparently, no one we asked had heard of Sacre Coeur either. We just kept walking until we came across a sign pointing to a very long and steep set of stairs, and decided to stop for something to eat before making the trek. And that is my Salade Nicoise story.
Here's the 'official' definition of what should and shouldn't be in this salad...it appears that I may have broken some of the rules, well with my boiled potatoes and steamed green beans...alas, my dreams of success in french cusine have been dashed ;)

Ingredients

2 or 3 potatoes (I like Yukon Gold), cut into small cubes and boiled
2 eggs, boiled and sliced
a few good handfuls of green and/or yellow string beans, ends removed and steamed
half of a cucumber, sliced into longish skinny pieces
a handful of cherry tomatoes, halved
6 to 8 leaves of lettuce ( I used the red leaved)
1 can of tuna (packed in oil-- I know, it's not as good for you as the one packed in water, but hey, it's still tuna, not steak...live on the edge)
a handful of olives
whatever else you think may taste good with the aforementioned ingredients

Dressing

In a mason jar or cup, add 1 part olive oil to 2 parts vinegar, some salt and pepper to taste
(and some garlic powder too)
If you have fresh herbs like oregano, thyme, dill, basil, parsley...mince some and add them to the mix.

Place the lettuce at the bottom of a serving platter and arrange the rest of the ingredients 'nicely' around the platter.
Drizzle with the dressing right before serving.
