Pan Bagnat (Provençal Tuna Sandwich)
My parents made a version of this sandwich from the Time Life Foods of the World cookbook series. We loved it. Loaded with different ingredients, bathed in a vinaigrette (the title means "bathed bread"), weighted down and left for all the flavors to meld — it was the perfect summer meal. So I was intrigued when Cooks Illustrated had their own version and tried it out last weekend. Theirs is more like a Salade Niçoise than the one I grew up with, but I love Salade Niçoise so that was no bad thing! It was truly delicious, simple to assemble (though requiring about an hour), and perfect for hot weather. Note: We had extra pieces of this in the fridge for up to a week as we slowly consumed them for lunch (or breakfast!). It held perfectly well and could be made well ahead of time for a party or picnic if you let it come up to room temperature.
