It's Monday definition day!
The first time I ordered a Nicoise salad, I was in college. I don't remember how I pronounced it, and even today, I often stop myself before pronouncing it -- second-guessing myself. The correct pronunciation is 'ni-swaz' (it's French).
The salad includes tomatoes, green beans, tuna and anchovies and is often accompanied with hard-boiled eggs and olives. Traditionally, it included raw red peppers, shallots and artichoke hearts, new potatoes or other cooked vegetables.
Here is a recipe offered by Chef Alice Waters of Chez Panisse.
