Beet Tart with Beet Green Pesto

My husband Lulu has been harvesting the most beautiful vegetables this season. I cook depending on what's available in our vegetable box, and today, I played around with red and golden beets. Nothing went to waste. I made a beet leaf (it's edible!) pesto that I used as the filling for a -- you guessed it -- beet tart. 

I recently discovered fellow blogger Béatrice Peltre's new cookbook that shares the name of her lovely website, LaTartineGourmande.com. I adapted her savory crust recipe for this dish, and I was very pleased with the result. The xanthan gum dough holds together much better, so I'm definitely going to keep this tip in mind.
