For the flakiest results, keep the puff pastry cold and work quickly; if it softens, chill the assembled log for 10–15 minutes before slicing to get cleaner rounds. You can substitute kale for spinach but cook it a bit longer to soften, and feel free to add finely chopped sun-dried tomatoes or olives for brightness. Red lentils are not recommended as they become too soft; green or brown hold shape best. Make ahead by preparing the filling up to 3 days in advance or freezing the unbaked sliced pinwheels; bake from frozen, adding 3–5 minutes. Serve with a simple lemon-tahini or marinara dip to complement the savory filling.
