For the pinwheels, preheat the oven to 450F. Line a baking sheet with parchment paper or a silicone liner. Unfold the puff pastry and use your fingers to stretch it in all directions just a bit. Spread the pimento cheese all over the puff pastry. If using, sprinkle hot sauce over top. Use your fingers to roll the puff pastry into a tight log with the pimento cheese, then cut into 1-inch rounds. Arrange the rounds on the baking sheet with 2 inches space in between. If using, spray with cooking spray and sprinkle with coarse salt. Bake 15-20 minutes until puffy and golden. Let cool 5 minutes or so before serving. Enjoy!
For the pimento cheese, combine all ingredients and adjust seasonings to your preference. If the cheese mixture seems very dry, add a bit more sour cream and mayo 1 tablespoon at a time.
