Summer's Bounty Thyme Galette

Directions

1. Make dough: In a small bowl, stir together the yogurt, lemon juice, and water and refrigerate. Whisk stir the flour and salt in a large bowl. Sprinkle bits of butter over dough and using a pastry blender or your fingertips, work it into the flour until the mixture resembles coarse meal, with the biggest pieces of butter the size of tiny peas. Add the thyme leaves. Mix the liquids into the butter-flour mixture with your fingertips or a wooden spoon until large lumps form. Pat the lumps into a ball. Wrap with plastic and refrigerate for 1 hour, or up to 2 days. Also freezes well.
2. Make filling: In a large sauté pan with a lid, add olive oil, tomatoes, and salt, then cover and heat over high heat. Roll the tomatoes around from time to time so that they cook evenly and don't burn. In a few minutes, you’ll hear some putts and pops as the tomatoes burst a little. When most have, remove lid, turn heat down to medium and add diced zucchini. Saute for two minutes, until they soften. Add chickpeas and kale and cook one minute. Add scallions, just stirring them in, then turn off heat. Add thyme and basil. Adjust seasonings if needed. Transfer mixture to a large plate and spread it out, so that it will cool faster. You want it cooled to at least lukewarm before assembling the galette.
3. Assemble galette: Heat oven to 400 degrees. On a floured counter, roll the dough out into a 12-inch round; it's fine that it doesn't have perfectly rounded edges. Transfer to a parchment-lined baking sheet; I like to fold my dough gently, without creasing, in quarters then unfold it onto the baking pan. Spoon the tomato-zucchini mixture into the center of the dough, leaving a 2-inch border, using a slotted spoon to leave behind any liquid. Fold the border over the filling, pleating the edge to make it fit. The center will be open.
4. Bake the galette: For 30 to 40 minutes, or until puffed and golden brown. Remove from the oven and let stand for 5 minutes, then slide the galette onto a serving plate. Cut into wedges and serve hot, warm or at room temperature. (Adapted from Smitten Kitchen.)
