For best results, use a high-quality puff pastry made with butter. This will ensure a richer flavor and flakier texture. Don't overfill the pinwheels, or they may be difficult to roll and slice. A thin, even layer of filling is key. If you're short on time, you can use pre-cooked bacon bits instead of cooking the bacon yourself. These pinwheels can be assembled ahead of time and baked just before serving. Simply prepare them up to the chilling step, then cover and refrigerate for up to 24 hours. Experiment with different flavors by adding other ingredients such as grated Parmesan cheese, sun-dried tomatoes, or fresh herbs like dill or parsley.
