You could dress this up with some black olives or branches of thyme baked with the endive.
I bought puff pastry for this tart because I felt like it. (Actually, I had a gazillion things to do and there are worse problems in the world than using store-bought puff pastry made with all butter.) But if you want to make your own, you're welcome to. If you'd rather use a standard tart dough for this, make the tart dough that goes with this
quiche recipe.
If you like a lot of cheese, have some extra bits handy to strew over the finished tart, when it's warm from the oven. (The heat of the tart should melt the cheese, but you can coax it along with a butter knife.) Chopped chives or parsley would make a nice garnish.
