Whip up this faster (but just as scrumptious) version that uses frozen puff pastry.
1 sheet frozen puff pastry dough
1 egg white, beaten
1 tablespoon freshly grated lemon zest
1 1/2 teaspoons finely chopped fresh thyme
1 1/2 teaspoons coarse sea salt
How to Make It
Preheat oven to 375°. Thaw 1 sheet puff pastry dough according to package directions, and place it on a lightly floured work surface. Brush pastry with beaten egg white, then sprinkle with lemon zest, chopped fresh thyme, and sea salt. Cut into 1/2-inch-wide strips with a pizza cutter; transfer to a parchment paper-lined baking sheet. Bake for 14-15 minutes or until lightly browned.
